Hi, thanks for sharing your work.
In my case, I have a reference folder (fdir1), and about 50 target folders (fdir2), each containing hundreds of images. It takes a long time to calculate the score by default fid.compute_fid(fdir1, fdir2)
. It seems it is chocked by the CPU. Is there any way to speed up it?
Dear all,
I wonder whether this module can be applied to evaluate video quality.
Thanks,

Hi,
Thanks for maintaining the library for GAN research!
I noticed that the KID implementation in this repository is quite different from the official KID implementation
Could the author explain a bit about the differences?
Best,
Hubert
From 3 mins on a100 it went to 40 mins.
Also, Pytorch added antialiasing to interpolation, should it be used for speding up calculations?
Hi!
Uppercase JPEG extension ignored by get_folder_features
I've noticed this issue while making custom statistics from a folder with .JPEG files.
It seems like it has been thought of here for processing .zip
Line 138 in b1d8934
Lines 140 to 141 in b1d8934
Probably the easiest fix is to expand the EXTENSIONS with the upper-case versions
Hello, I think the following implementation of the Fréchet distance is faster than the current one and would allow to drop the scipy
dependency.
def frechet_distance(mu_x: Tensor, sigma_x: Tensor, mu_y: Tensor, sigma_y: Tensor) -> Tensor:
a = (mu_x - mu_y).square().sum(dim=-1)
b = sigma_x.trace() + sigma_y.trace()
c = torch.linalg.eigvals(sigma_x @ sigma_y).sqrt().real.sum(dim=-1)
return a + b - 2 * c
The implementation is based on two facts:
However, it is required when using fid.make_custom_stats()
. I used pip.
Also, the README instructs one to pip install -r requirements.txt
while such a file is not present.
Is the teaser figure depicting problems of downsampling still the same, given the new Pytorch 2.0 update? (i.e., is this issue the same for the current implementation of PyTorch bilinear...).
I know it is not a direct issue on the repo, but I could not find the answer or any updates about this.
Thanks for the great work!
I was trying to load a Generator from Progan implementation in pytorch. This generator receives a tensor of size
(batch_size, Z_DIM, 1, 1)
as input, where Z_DIM
is the latent vector dimension (e.g. 512). The code in
cleanfid/fid.py, line 214 accept an input of size z_batch = torch.randn((batch_size, z_dim)).to(device)
,
which is a 2D tensor, suitable only for non-RGB images (like in Vanilla GAN or other examples). I think
the code should also support 4D tensors for RGB images, as most GAN implementations accept
4D tensors as inputs to their generators.

I'm very new to all this so this question might not make sense, but am I right in the assumption that FID relies on some pretrained model to evaluate the difference between the "fake" and "real" folders? If so, I assume such a model was trained only on generic photo content, which will limit its efficiency for drawn pictures and anime in particular. Or just having a large enough "real" folder will be enough?
If not, do I have to fine-tune said model for this specific content or there are pretrained models for 2D images that I could use here?

Hi Gaurav, thanks for sharing this amazing tool! I spot a block of suspicious lines that might worth your attention. Specifically, this resizing function of the default "clean" resizer:
Lines 43 to 52 in d2a10b1
It seems to me that the output_size
in L47 (s1, s2) supposes to be a (w, h) tuple whilie L48 expects it as (h, w). What do you think? This might mean that the default resizer only works for square output resolution.
Shouldn't be a big problem since it does not affect default behavior.
May I ask what will be the difference if I directly call the function instead of clarifying its mode?
Hi there, thanks for this package, it's really helpful!
On a cluster with multiple GPUs, I have my model on device cuda:1
.
When calculating FID with a passed gen
function, new samples are generated during FID calculation. To that end, a model_fn(x)
function is defined here:
clean-fid/cleanfid/features.py
Lines 23 to 25 in bd44693
and if use_dataparallel=True
, the model will be wrapped with model = torch.nn.DataParallel(model)
.
Problem: DataParallel
has a kwarg device_ids=None
which defaults to all the available devices and then selects the first device as the "source" device, i.e., cuda:0
. Later it asserts that all parameters and buffers of the model are on that device.
Now, if device_ids is not passed, this will result in an error because my model device is different from cuda:0
.
I am wondering why DataParallel
just hard codes everything to the first of all available devices, but there is a solution on the cleanfid
side for this problem.
Solution: pass device_ids with the device of the model:
if use_dataparallel:
device_ids = [torch.cuda.current_device()] # or use next(model.parameters()).device
model = torch.nn.DataParallel(model, device_ids=device_ids)
def model_fn(x): return model(x)
I would be happy to make a PR fixing this. Unless I am missing something?
Cheers,
Jan
This version is pretty old...I just want to know why is it being pinned, as it conflicts with many of the other libraries I have.
Trying to use CLIP FID after pip install clean-fid

Thanks for sharing this great work. I'm just wondering about the reasons behind resize the image per channel and not resizing it as 3 channels array. I'm referring to this piece of code in the file resize.py
.
def resize_single_channel(x_np, output_size):
s1, s2 = output_size
img = Image.fromarray(x_np.astype(np.float32), mode='F')
img = img.resize(output_size, resample=Image.Resampling.BICUBIC)
return np.asarray(img).clip(0, 255).reshape(s2, s1, 1)
def resize_channels(x, new_size):
x = [resize_single_channel(x[:, :, idx], new_size) for idx in range(3)]
x = np.concatenate(x, axis=2).astype(np.uint8)
return x
I hope this is the way to ask questions here since It's my first time to ask a question on Issues instead of submitting an issue.
Thanks for your understanding.
Looks like the actual number of generations is rounded up to the nearest multiple of batch size:
Line 199 in fca6718
for the Line 391 and 396 in compute_kid(), I think the 'None' should actually be 'feat_model'
Line 391 in 55ec168
Passing device="cpu"
and model_name="clip_vit_b_32"
crashes with the following error:
RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cpu and cuda:0! (when checking argument for argument weight in method wrapper___slow_conv2d_forward)
Hi,
Thanks for your contribution on GAN research!
We tried to get clean-fid for the images generated by styleganv2 using your code. However, the score was about 24, which was very different from the results reported in the paper. 50k images were generated using official checkpoints and calculated using pre-computed datasets statistics.
How to solve it?
Best,

We follow the StyleGAN-ADA to extract FFHQ256 from tfrecord file. However, when I computed the statistic, it results in different statistics from your pre-computed trainval70K. I want to know whether the calculation steps have changed?
Recently, I've come across a post on LinkedIn that describes how we should carefully choose the right resize
function while stressing the fact that using different libraries/frameworks leads to different results. So, I decided to test it myself.
Click here to find the post that I took the inspiration from.
The following is the code snippet that I've edited(using this colab notebook) to give the correct way of using resize methods in different frameworks.
import numpy as np
import torch
import torchvision.transforms.functional as F
from torchvision import transforms
from torchvision.transforms.functional import InterpolationMode
from PIL import Image
import tensorflow as tf
import cv2
import matplotlib.pyplot as plt
from skimage import draw
image = np.ones((128, 128), dtype=np.float64)
rr, cc = draw.circle_perimeter(64, 64, radius=45, shape=image.shape)
image[rr, cc] = 0
plt.imshow(image, cmap='gray')
print(f"Unique values of image: {np.unique(arr)}")
print(image.dtype)
output_size = 17
def inspect_img(*, img):
plt.imshow(img, cmap='gray')
print(f"Value of pixel with coordinates (14,9): {img[14, 9]}")
def resize_PIL(*, img, output_size):
img = Image.fromarray(image)
img = img.resize((output_size, output_size), resample=Image.BICUBIC)
img = np.asarray(img,dtype=np.float64)
inspect_img(img=img)
return img
def resize_pytorch(*, img, output_size):
img = F.resize(Image.fromarray(np.float64(img)), # Provide a PIL image rather than a Tensor.
size=output_size,
interpolation=InterpolationMode.BICUBIC)
img = np.asarray(img, dtype=np.float64)
inspect_img(img=img)
return img
def resize_tensorflow(*, img, output_size):
img = img[tf.newaxis, ..., tf.newaxis]
img = tf.image.resize(img, size = [output_size] * 2, method="bicubic", antialias=True)
img = img[0, ..., 0].numpy()
inspect_img(img=img)
return img
image_PIL = resize_PIL(img=image, output_size=output_size)
image_pytorch = resize_pytorch(img=image, output_size=output_size)
image_tensorflow = resize_tensorflow(img=image, output_size=output_size)
assert np.array_equal(image_PIL, image_pytorch) == True, 'Not Identical!'
# assert np.array_equal(image_PIL, image_tensorflow) == True, 'Not Identical!' --> fails
assert np.allclose(image_PIL, image_tensorflow) == True, 'Not Close!'
# assert np.array_equal(image_tensorflow, image_pytorch) == True, 'Not Identical!' --> fails
assert np.allclose(image_tensorflow, image_pytorch) == True, 'Not Close!'
# tensorflow gives a slightly different values than pytorch and PIL.
which gives us the following results:
Therefore, TensorFlow, PyTorch, and PIL give similar results if the resize
method is used properly like in the above snippet code.
You can read my comments on linkedin to find out how I came to this solution.
The only remaining library is OpenCV which I'll test in the future.
Have a great day/night!

Dear clean-fid group,
Thank you for sharing this great work, I really like it.
You mention in the paper that the PIL implementation is anti alias. But the PIL library could not back backpropagate gradient. Do you have plan to implement a way resize function that support anti alias and backpropagation? Or could you inform me the right way to do this?
I believe this will be very usefull for the community. For example, we invert a real image to the latent space of GAN, usually we dont use the full resolution image. The generated image must downsampling then compare to real image (LPIPS), and then backpropagate gradient. This is the implementation in Stylegan-ada (https://github.com/NVlabs/stylegan2-ada-pytorch/blob/main/projector.py#L97), it uses the torch resize function which could not anti alias as you mentioned in the paper.
Thank you for your help.
Best Wishes,
Alex

Thanks for this excellent repository. Comparing with https://github.com/mseitzer/pytorch-fid, I would like to extract features from different pooling layers like the first max pooling features (64), second max pooling features (192), pre-aux classifier features (768), and final average pooling features (2048) and compare FID scores. I believe the default option in your case is extracting the features from the final average pooling layer. Correct me if I am wrong.
from cleanfid import fid
fdir1 = '/content/gdrive/MyDrive/syn'
fdir2 = '/content/gdrive/MyDrive/orig'
score = fid.compute_fid(fdir1, fdir2)
print(score)
Is there an option to modify the function call to extract features from different layers and compare the scores? Thanks in advance.

Hi,
I am a little confused that should the resolution of images in 2 folders be the same or different (folder1: 256x256, folder2: 1024x1024)? If not, can we use PIL to resize it or use torch transform resize?
Many thanks.
When I download one from internet, how can I use it directly.
I want to cleanly calculate the FID score because I had some differences due to resizing. I appreciate the work you have done to make the process more consistent.
I am running the module on PyTorch 1.9.0, CUDA 11.2, and get the following error when calculating the FID score in the "clean" mode using the "torchscript_inception" model from https://nvlabs-fi-cdn.nvidia.com/stylegan2-ada-pytorch/pretrained/metrics/inception-2015-12-05.pt:
RuntimeError: MALFORMED INPUT: lanes dont match
On the following line:
clean-fid/cleanfid/features.py
Line 47 in 9e1c478
It is a very peculiar error coming from this file:
https://github.com/pytorch/pytorch/blob/fce85480b97d8d79e92e11fbcd3c03a25ae446e0/torch/csrc/jit/tensorexpr/types.h#L35
I'm not familiar with TorchScript but maybe it has something to do with the model being composed/uploaded in another Pytorch version. It is probably better to ask in the Pytorch github what causes this.
However, I want to ask if just using the regular InceptionV3 model provided here would give the same FID score / would also be good practice. In short: calculate FID in "clean" mode but use the "pytorch_inception" model
Hello, I tried using the package, but its throwing this runtime error. I checked image size mismatch, whether they are corrupted or not but no leads as to what is causing this.
This code is from fid.py line 459-470.
elif gen is not None:
if not verbose:
print(f"compute FID of a model with {dataset_name}-{dataset_res} statistics")
score = fid_model(gen, dataset_name, dataset_res, dataset_split,
model=feat_model, z_dim=z_dim, num_gen=num_gen,
mode=mode, num_workers=num_workers, batch_size=batch_size,
device=device, verbose=verbose)
return score
# compute fid for a generator, using images in fdir2
elif gen is not None and fdir2 is not None:
There is no way we enter the last elif, so I can't compare my generator with images in fdir2. Is this intentional?
I tried fid.compute_fid function with cifar10 dataset.
It went perfectly until last week.
Seem like the dataset's URL is no longer supported.
Does anyone have the same error as me?

Would be possible to add pre-computed statistics for MSCoco dataset?
Hi,
I am facing the Imaginary component issue unless I have more than 2048 images in each folder.
I use this line of code to compute it.
fid_score = fid.compute_fid(source, target, mode="clean", verbose=True, dataset_split="custom", use_dataparallel=False)
The weird thing is that happens only on validation set, on a subset of training set it works well. Unless I perform exact same operations on both, as saving model predictions and targets using torchvision.
I am using clean-fid==0.1.35
CUDA 11.8
Python 3.10.13
numpy==1.26
torch==2.0.1
Debian 11
Thanks for tyour help in advance ;)
My dataset has nonsquare samples, so on training, I'm doing random crop and for validation, I'm calculating fid with center cropped copy of dataset.
Would be cool to have some option for passing my own transform, for example.
I am trying to compute KID, but it is generating negative values. Can KID be a negative number?
Here is the code that I used:
`
from cleanfid import fid
fdir1 = my_folder1_path
fdir2 = my_folder2_path
kid_score = fid.compute_kid(fdir1, fdir2)
`
Each folder has only 6 images. My kid_score is -0.0406.
Could someone please help me understand why the KID is less that zero?
Thank you,
Chandrakanth
Hi, thanks for your work,
I wanted to calculate the FID score between multiple generations of the same input image. I setup my directories such that directory 1 contains n generated image and directory 2 contains n copies of the input image. Is this ok way to go about this ? I ran into the following error while doing this :
RuntimeWarning: invalid value encountered in scalar divide arg2 = norm(X.dot(X) - A, 'fro')**2 / norm(A, 'fro')
Thank you
