I have code in the backend of django project which is hosted on PythonAnywhere that uses tensorflow. However, I am getting this error in server log and a 502 Bad Gateway server error

Please let me know how to use tensorflow on pythonAnywhere or any configurations i have to add.

Thanks

Hmm, does follow these instructions for a notebook work for you?

I'm having the same error.

"This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN)to use the following CPU instructions in performance-critical operations" even though it runs fine in other environments.

I've just signed up for this service, and it seems good, but not sure how to solve this, as installed Tensorflow into the instance.

do you have this error Could not load dynamic library 'libcuda.so.1';? Or the error / warning that you quoted?

I dropped to version 3.6 of python and it's working fine. I think the issue was getting the right version of Tensorflow to work with the VM.

I read that it was a compatibility issue, but sure I can work with the pre-installed version on 3.6 for now.

That's interesting -- glad to hear you got it working, anyway! Where did you read about the compatibility issue?
