Google Coral support about compreface

[gtxaspec]

Incorporating Google Coral TPU support in CompreFace would be a game-changing move. Not only has this feature demonstrated notable effectiveness in Frigate, but it's also recognized for its superior performance enhancements.

Its integration with CompreFace would supercharge face recognition capabilities, accelerating processing times. This upgrade could broaden CompreFace's appeal, making it more accessible and valuable for a diverse user base. Enthusiastically anticipating the potential implementation/incorporation of this feature! +1

Hi @pospielov,

I have made progress with EFRS-1114 and managed to get detection working using my Coral USB Accelerator.

There are a couple things:

• I've changed UWSGI to run as root. Running as www-data would require usermod -a -G plugdev www-data for www-data to get permission to work with the Edge TPU
• The commit bd8b682 needs to be reverted
• The container EITHER needs to be privileged or and have /dev/bus/usb mapped; EDIT: It needs both to work.

I've managed to get it working that way. However I only started using CompreFace today and don't fully understand the architecture behind it yet. I'm using the single container approach and I think I can't just replace the calculator?

Check out here.

[pospielov]

https://github.com/exadel-inc/CompreFace/blob/EFRS-1114/embedding-calculator/tpu.Dockerfile.full
here is the new docker file. As I understand in Irina's environment it didn't see the Google Coral.
Probably the problem is with MacOS
If you have Linux, you can try it out - probably it already works.
Here is a doc with example of using Google Coral with docker:
https://medium.com/star-gazers/running-tensorflow-lite-at-the-edge-with-raspberry-pi-google-coral-and-docker-83d01357469c
I think to build it you can use this command:
docker build -t embedding-calculator --build-arg SKIP_TESTS=true .
to run, this:
docker run -p 3000:3000 --privileged -v /dev/bus/usb:/dev/bus/usb embedding-calculator
Then if everything ok in logs, you can open swagger in the browser:
http://localhost:3300/apidocs
and then invoke /find_faces request. If everything ok - then we can try to put it into docker-compose and check the whole system

This build problem could be fixed by adding PyYAML==5.4.1 to requirements.txt file
So yes - if you merge master into this branch it should fix this problem. But it could appear other problems, who knows. So I would recommend fixing it directly in requirements.txt file, and merging master only after make sure that everything works

[iamacarpet]

CUDA is the name of nVidia’s GPGPU cores, and from the file names, it looks like it is using TensorFlow, rather than TensorFlow Lite (required for Coral).

In the PR’s main comment block, she referenced a function where you have to pass in the parameter of “TPU”, but I didn’t understand where that referenced.

[pospielov]

First, this would be great!
Second, it's not so simple

There are two problems to solve:

1. Add Google Coral support
2. Build it for arm devices

What I suggest is first try to build CompreFace with Google Coral support and then try to build it for arm devices.

We have a branch https://github.com/exadel-inc/CompreFace/tree/EFRS-1114, which is quite old, but it's a good idea to start from it. Could you try if it builds and works with Google Coral?

There are two docker files:
https://github.com/exadel-inc/CompreFace/blob/EFRS-1114/embedding-calculator/tpu.Dockerfile
https://github.com/exadel-inc/CompreFace/blob/EFRS-1114/embedding-calculator/tpu.Dockerfile.full
Not sure what is the difference, but it's good to start researching from them

[jmorille]

Very nice 2 years killing feature.

Do you have a working TPU Docker Image for Beta test ?

• A TPU tag in https://hub.docker.com/r/exadel/compreface-core/tags ?

[pospielov]

I totally agree with you that support of Google Coral accelerator would be great.
But I described all the problems here:
#519 (comment)

[iamacarpet]

With the PR #580 for Coral support, is this looking any more possible?

I tried looking through the contents of the PR but couldn't actually tell if it's possible to start using without further code changes.

@pospielov or @iamrinni , can you comment?

[pospielov]

Irina did a great job and managed to run compreface-core functionality on Google Coral.
The problem she faced is putting this functionality into a docker container. There are instructions on how to use Coral on Linux, but she has MacOS.
Unfortunately, she left the project, and this task is stuck. I don't have time for it for now. Probably I'll return to it next year or if we find another contributor with Google Coral

[iamacarpet]

Thanks @pospielov ,

Can you offer any advice on how to get moving with it?

My python skills are pretty much nonexistent, but if it’s just wrapping everything up in Docker, I might be able to help.

The PR that is pending seems to have Docker images included… Did these not work on testing?

Haven’t properly gotten to grips with the architecture to know how everything hangs together yet, but is the ideal that the only thing that needs replacing is the container(s) running TensorFlow and then it should “just work”?

I understand that might be a time consuming question to answer, only if you have time and any hits in the right direction would be appreciated.

[patatman]

Sorry I'm jumping onboard this issue, but I wanted to share my progress:

So I tried running this in my current Test env, and ran into some issues. (Unraid os, which is a stripped linux version)
Fixed most of them, but I couldn't fix some of them(mainly python related, and because of the stripped OS)
So I'm currently spinning up a Ubuntun20.04 VM in my lab to see if I can get this working. I have a spare Coral that I'm going to use for testing.
If I make a succesfull build + running the Swagger stuff I'll let you know.

[patatman]

Small update:
Container building went successful, but I can't seem to run it.

I noticed the branch from Irina was behind the Master, so I did a merge from master and now it's building again. Unfortunately the build takes quite long, so I'm just waiting on that to see if that fixes the issue.

[patatman]

Last update:
Got the container running, the merging from the master seems to have done the trick.
I'm currently trying to scan a image using the Swagger ui, but I'm getting the following error:

2021-11-22 17:10:35.050104: E tensorflow/stream_executor/cuda/cuda_driver.cc:351] failed call to cuInit: UNKNOWN ERROR (303)

I currently don't have time to debug any further, will continue a bit later. Maybe someone can continue based on what I provided.
I pushed my changed to my own fork here: https://github.com/patatman/CompreFace/tree/EFRS-1114

[patatman]

I continued today a bit, and I ruled out some issues:

• The USB is properly passed to the container
• Google Coral is working, tested this with the Google Example
  

It really look like this part is trowing the error:

2021-11-23 20:09:37.524992: E tensorflow/stream_executor/cuda/cuda_driver.cc:351] failed call to cuInit: UNKNOWN ERROR (303)

I'm not sure why though, and I'm not a programmer. If someone with better understanding of Python or this package is willing to help, that would be awesome! I'm open to do a pair-programming session to debug/solve this issue.

[patatman]

I had a closer look at the PR, but even after changing the code to:

    def _calculate_embeddings(self, cropped_images, mode='CPU'):
        """Run forward pass to calculate embeddings"""
        if mode == 'TPU':
            calc_model = self._embedding_calculator_tpu
        else:
            calc_model = self._embedding_calculator_tpu
            # cropped_images = [prewhiten(img).astype(np.float32) for img in cropped_images]

Basicly forcing it to always use the _embedding_calculator_tpu part(If I'm correct). It still gives the same error.

[patatman]

The error below doesn't seem Google Coral related, it also generates this error if I use the CPU.

2021-11-23 20:09:37.524992: E tensorflow/stream_executor/cuda/cuda_driver.cc:351] failed call to cuInit: UNKNOWN ERROR (303)

I've debugged a ton, and currently I'm stuck on this error:

{
  "message": "RuntimeError: Node number 3 (CONV_2D) failed to invoke.\n"
}

As soon as I try to invoke the find_faces api it generates this error.
The Status api works as expected, and the program doesn't crash. It's just that specific request generates an error.
If I look into that error, some people are saying it's related to the model used. I'm not familiar enough to debug this any further.

Anyone have any ideas to continue? Currently stuck

[pospielov]

Kind of a strange error.
I tried to build by myself. First - I took the clear branch and fixed only requirements.txt as I mentioned.
Then build with:
docker build -t embedding-calculator --build-arg SKIP_TESTS=true -f tpu.Dockerfile .
Then run with and without Google Coral :
docker run -it --name=test -p 3000:3000 embedding-calculator
It worked normally. I mean according to code by default it will use CPU, not TPU.

Then I changed the file coralmtcnn.py the same way as you did.
Built and run with this command (and with Google Coral):
docker run -it --privileged -v /dev/bus/usb:/dev/bus/usb --name=test -p 3000:3000 embedding-calculator
When I tried to run the find_faces endpoint I got this error:

Traceback (most recent call last):
    File "/usr/local/lib/python3.7/site-packages/flask/app.py", line 1950, in full_dispatch_request
    rv = self.dispatch_request()

    return self.view_functions[rule.endpoint](**req.view_args)
    File "./src/services/flask_/needs_attached_file.py", line 32, in wrapper
    return f(*args, **kwargs)
    File "./src/_endpoints.py", line 72, in find_faces_post

    raise exceptions.PluginError(f'{plugin} error - {e}')
    src.services.facescan.plugins.exceptions.PluginError: coralmtcnn.Calculator error - Failed to load delegate from libedgetpu.so.1

Looks like the problem with a library.
I also got this warning:

{"severity": "DEBUG", "message": "Falling back to TensorFlow client; we recommended you install the Cloud TPU client directly with pip install cloud-tpu-client.", 

I can't say where is the problem, I need to dig deeper to fix it.

[patatman]

So I tested again with the clean branch like you mentioned above.

1. Adjust requirements.txt
2. Build and run successful
3. adjust embedding-calculator/src/services/facescan/plugins/facenet/coralmtcnn/coralmtcnn.py to ONLY use Coral
4. Build and run Successful!
5. remove Coral from USB (while container is running)
6. Still works? So it wasn't using the Coral after all.
7. check code inside container, to make sure it's running the version where both are using self._embedding_calculator_tpu
8. What is happening? haha
   I'm doing some more tests tomorrow.

Your error Failed to load delegate from libedgetpu.so.1 suggests it can't find the Coral. Make sure you have the coral plugged in before you run the container. I was trying to replicate this when I was running step 5 haha.

[pospielov]

Do you have the same error as me if you plug out Coral?

[patatman]

No, I can't seem to get the code to run of the Coral. It doesn't matter if I have it plugged in, and with the code adjustment to force is. It will always use the CPU instead of coral.

[beetlezap]

I can gladly be part of testing on my RPI4+Google Coral running Frigate today

[isaacolsen94]

Any updates on support for Google Coral?

[pospielov]

Unfortunately no, we don't have contributors with Google Coral now

[archef2000]

I know a bit of python and have a raspberry pi 4 8gb 64bit with a coral ai what is the latest code with coral support.
I would be happy to help.

[archef2000]

Are these Dockerfiles ARM64 compatible?

[pospielov]

No, we don't have ARM-compatible dockerfiles. This is another challenge

[LordNex]

I have all that and a Jetson Nano along with a test VMWare environment running on a Dell PowerEdge R620. Although I'm no programmer I do have 26 year of IT background. Mainly networking

[pospielov]

#610 (comment)
I described here what we need to do to support ARM devices.
Will you be able to help with it?

[archef2000]

#610 (comment) I described here what we need to do to support ARM devices. Will you be able to help with it?

I would love to.

[LordNex]

#610 (comment)

I described here what we need to do to support ARM devices.

Will you be able to help with it?

So basically run through what you did on the Jetson and that should compile an image?

[leccelecce]

I would like to help with this. Java programming background but happy with a bit of Python, Typescript etc. Only problem is: my Coral USB order is saying delivery 05/2023 :/ hoping they get some earlier stock!

[LordNex]

I'd like to see it run off the Nano. I have Frigate using the Coral for Object detection. Would be nice to use all those cuda cores for facial recognition. For now I just have it running with Double Take in a VM on a PowerEdge R620 so it's just using xeon processor cores. Although I'm thinking about trying to find an old nvidia card go throw in there and see if that'll help.

[ninjasstudio]

I have 2 pci-e m.2 corals and I'd be happy to help test/debug this weekend.

Corals: 1 Daul-edge m.2 TPU, 1 single M.2 TPU using 2 M.2 to pci-e adapter cards.

Setup: Running Frigate (GPU inference -Nvidia GTX 1080)/Doubletake/Compreface ( CPU inference- Intel Xeon E3 1280). hosted in Docker using Home Assistant OS add-ons as a qemu client on an Ubuntu 22.04 Host.

I started working on adding Compreface GPU builds to the single container builds for use as a home assistant addon last weekend but would much rather do face detection on the corals.

I don't have the USB corals but hopefully its the same python api with config differences.

[pospielov]

Not sure what you mean by "adding Compreface GPU builds to the single container builds".
https://hub.docker.com/r/exadel/compreface/tags
There are already tags with GPU support.
Regarding USB corals - we don't have contributors with Google Corals, so adding its support was frozen.

[archef2000]

I have one and would be happy to help bit i only have a RPI

[muebau]

I thought to make the same offer 😄

[just5ky]

Hi, I have two mini PCIe coral TPUs currently being used with Frigate only.
I really want to use CompreFace with it. I will be happy to help develop this feature by testing it and providing logs for troubleshooting.
Running it on i3-12100F, 32 GB RAM, Quadro T600.
I also have RPi4 but no USB Coral to test ARM build.

P.S i don't know much about coding, but I have build and maintained multi-arch docker containers

[just5ky]

First, this would be great! Second, it's not so simple

There are two problems to solve:

1. Add Google Coral support
2. Build it for arm devices

What I suggest is first try to build CompreFace with Google Coral support and then try to build it for arm devices.

We have a branch https://github.com/exadel-inc/CompreFace/tree/EFRS-1114, which is quite old, but it's a good idea to start from it. Could you try if it builds and works with Google Coral?

There are two docker files: https://github.com/exadel-inc/CompreFace/blob/EFRS-1114/embedding-calculator/tpu.Dockerfile https://github.com/exadel-inc/CompreFace/blob/EFRS-1114/embedding-calculator/tpu.Dockerfile.full Not sure what is the difference, but it's good to start researching from them

I do not see any error in tpu.Dockerfile build logs, not sure why its crashing.

Single container build uses compreface-core image as a base and then adds everything else inside.
So the task is still to make a proper compreface-core image so that you can build a single image later.

Single container build uses compreface-core image as a base and then adds everything else inside. So the task is still to make a proper compreface-core image so that you can build a single image later.

Right, that much I understand. How do I make a "proper compreface-core" image? I've built and run the embedding-calculator with Coral support and I've a working container for that, but I'm afraid without further guidance I'm unable to go any further than that.

[pospielov]

compreface-core is the name for embedding-calculator image.
Have you managed to build embedding-calculator docker image?
The easiest way to build it:

1. Go to ./dev folder
2. Run docker compose build compreface-core

[meks007]

Not yet, since I've got no reply. I'll try with your instructions.
EDIT: I do have a local image, can I upload it somewhere?

[pospielov]

To upload the image, you can use
docker login - to login to your docker account
docker push <the name of your image>
the name of your image should contain the name of your docker account
you can see examples here:
https://docs.docker.com/engine/reference/commandline/push/#examples

Just wanted to confirm, is Google Coral TPU M.2 working? To also clarify, since I'm using the M.2, it would put /dev/apex_0 or make available to compreface-core image right?

Just wanted to confirm, is Google Coral TPU M.2 working? To also clarify, since I'm using the M.2, it would put /dev/apex_0 or make available to compreface-core image right?

Did this work for you with CompreFace?

Currently, I'm using Coral TPU passed through via LXC>Docker>Frigate. Additionally, I have Intel HWAccel functioning in Frigate, but my Coral is connected via USB. However, if I have the Coral working seamlessly with Frigate, there's no reason to believe, as you've demonstrated here, that I can't utilize the same device callouts in my docker-compose for CompreFace, Deepstack, and CodeProject to also access the Coral?
