AttributeError: module 'lpips' has no attribute 'LPIPS'

[outfielder]

I have done a pip install lpips as instructed in the repo's README and copied an pasted the example code given:

import lpips
loss_fn_alex = lpips.LPIPS(net='alex') # best forward scores
loss_fn_vgg = lpips.LPIPS(net='vgg') # closer to "traditional" perceptual loss, when used for optimization

import torch
img0 = torch.zeros(1,3,64,64) # image should be RGB, IMPORTANT: normalized to [-1,1]
img1 = torch.zeros(1,3,64,64)
d = loss_fn_alex(img0, img1)

but I keep getting the following error:

Traceback (most recent call last):
  File "home/xyz.py", line 2, in <module>
    loss_fn_alex = lpips.LPIPS(net='alex') # best forward scores
AttributeError: module 'lpips' has no attribute 'LPIPS'

I know that it is installed, because I can right click on LPIPS in my IDE and it takes me to the source code, so I am confused as to why I am getting that attribute error.

I can see someone else had the same issue before me, but the issue is closed without any explanation as to how it may have been solved.

I have same problem.

I don't know if you have the same cause, but my problem is solved. I had named the file lpips.py to test lpips, so import lpips imported lpips.py itself, causing a circular reference. After changing the file name to lpips_test.py, it worked.

Genius! :) I had a same problem and this helped. Thank you. @outfielder May be you can check the current folder whether a 'lpips.py' file exists here?

Check & Rename the existing lpips.py files.

That's why，Thank you
