can't import LPIPS with this code

[Joon7330]

when run this code, it can't import the module named LPIPS.
How can I solve this problem?

Thanks. pip install lpips I think will be the fix. See https://github.com/richzhang/PerceptualSimilarity.

But the line of bash that is in this notebook is pip install -q git+https://github.com/S-aiueo32/lpips-pytorch.git so make sure that cell got run first.

Thanks for answering my question.

By the way, I have another error in Helper Functions session : line lpips_dist = LPIPS_Device(net_type='vgg', version='0.1') # ['alex', 'squeeze', 'vgg']
AttributeError: 'LPIPS_Device' object has no attribute 'chns'
Can you tell me how to solve it?

I'm sorry to bother you.

[thestephencasper]

I am unsure. It sounds like this is being triggered by a line of code that tries to access the attribute LPIPS_DEVICE.chns, but there is none. Maybe there is a typo somewhere in the notebook you're using that uses "chns".

Seriously, the code doesn't work. Can you run the code by any chance?
Once I get the ipynb file that you uploaded and run it, it doesn't run.
plz help me. @thestephencasper

[thestephencasper]

Thanks. I looked into it more deeply. There was a somewhat mysterious issue with lpips. I have made some changes and I believe it should be fixed (It just all ran for me in colab). Please see the new pushed notebook.

I'm so glad you found the error in what I said.
I couldn’t have done it without you @thestephencasper !! It works!!

I have had a lot of experience through the thesis and code you wrote, and I think I will be able to get a lot of help in the future.
