no attribute PerceptualLoss

[TouqeerAhmad]

Hi Manuel, I was trying to following your example to train dsgan but I am encountering the following error:

"module 'PerceptualSimilarity' has no attribute 'PerceptualLoss'"

when it tries to initialize the PerceptualLoss in loss.py. I have downloaded the PerceptualSimilarity and placed it in the directory 'real-world-sr/dsgan/'. I was able to successfully run the examples provided with the PerceptualSimilarity author. Can you please advise?

Thanks,
Touqeer

Are you by any chance using an older version of LPIPS. The following excerpt from LPIPS introduction points there are two versions:

"If you use LPIPS in your publication, please specify which version you are using. The current version is 0.1. You can set version='0.0' for the initial release."

Never mind about this issue. I was able to get rid of this by importing models and replacing ps with models when initializing the loss network. Specifically, following two lines should address this if anyone else gets the same error:

'from PerceptualSimilarity import models'
'self.loss_network = models.PerceptualLoss(use_gpu=torch.cuda.is_available())'

Hi Ahmad,
Thanks for your suggestion.
I download the original version, it can import now.
However, there is another problem.

Have u experienced this before?

@hcleung3325 I remember solving this by using torch==1.1.0

Sorry, I can't find "from PerceptualSimilarity import models".Where is the "models"? Can you share the code ?

PerceptualSimilarity

You can download the PerceptualSimilarity package.
Or I email you the package, what is your email?

Thanks for your reply. My email is 896385980@qq.com. Please!

The downloaded perceptualsimilarity works, but still reports an error:
AttributeError: module 'PerceptualSimilarity' has no attribute 'PerceptualLoss'.
The current lpips minimum version 1.0 cannot be reduced to 0.0.
I did not find models for the above solution.
Is there any other solution? Thank you!
