[demasakbar]

I have error message like this

The above exception was the direct cause of the following exception:

Heya, what environment are you running the aiyabot on?

Closing this issue due to no response.

I've had the same problem and in my case it was caused by the pytorch_model.bin being corrupted or something.

$ shasum core/MagicPrompt-SD/pytorch_model.bin
c11010a918a2ec2ab7029e4d16db044f6b205662  core/MagicPrompt-SD/pytorch_model.bin 

But it should be

$ shasum core/MagicPrompt-SD/pytorch_model.bin 
193180595d73e5463a17cdea187954f0f92860c6  core/MagicPrompt-SD/pytorch_model.bin

Problem was solved by deleting and re-downloading the file.
