Unable to run the mate-tool about hulk

[ApocalypseNAO]

Hello @schmidma

Thanks a lot for your help: problem solved !
Installing python 3.7 was indeed the key.

Hello,

First of all congratulations to the Hulks team for this excellent code framework!

I experience exactly the same issue as @Heodel with the mate tool: I can launch mate but I get exceptions when trying to connect to a real or simulated robot. So far I could not solve it. I tried two different versions of python, namely the 3.5.1 and 3.6.8 on Ubuntu 16.04.

Would you have any suggestion or research axis to solve this issue ?

Hey @ApocalypseNAO,

thanks for confirming the issue. I guess there is some dependency missing on your system as I am able to use mate in the version we released in this code release. You can find our dependencies in the top level folder of this repo in a file named pythonRequirements.txt

Can you start mate from the console and post the output? Also: Do you run mate inside a virtual python environment (venv)? If not I would suggest to do so as you won't pollute your global python packages with our requirements. You can then install our requirements using pip install -r pythonRequirements.txt (I highly recommend only executing this command in your venv). Let me know if you need help with that.

Hello, thanks for your reactivity !

As suggested I then installed the required packages in a virtual environment (I used which python to be sure). Once done, the command pip install -r pythonRequirements.txt gives the following result:

It seems that all the dependencies are satisfied. I can run mate (after un-setting the PYTHONPATH to avoid messing with opencv) but get the same bug as before when trying to connect to a simulated robot:

Hello!
In fact, I have exactly the same problem as @ApocalypseNAO and @Heodel, and I am really unable to find a solution by myself as well.
Can somebody help me, please?
It is a shame not to be able to use all the potential of your code because of that...

Hey @ApocalypseNAO thanks for providing this log,
if i read your log correctly you are using python in version 3.5 or at least the asyncio python library is based on version 3.5.
MATE as released in our 2018 CodeRelease needs a minimum 3.7 (possibly 3.6) as there are major changes in the use of asyncio library. Please try to use MATE with a newer version. If you encounter further problem please let us know.
