Dependency issues on deployed apps despite providing environment.yml file

☁️ Streamlit Community Cloud
1

Hi,
I had successfully deployed an app on Streamlit cloud which had been active for a while. But on checking now, the following error shows up:
My environment.yml mentions the transformers package as a dependency and the app was running after deployment. Why does it show this error now?

Maybe there is a mismatch between the python version and the packages you nailed in your environment.yml file.
Try this:

requirements.txt

pandas
scikit-learn
torchvision==0.13.0
torch==1.12.0
torchaudio==0.12.0
streamlit==1.15.2
transformers==4.20.1

Should I add these in a separate requirements.txt file in addition to the existing environment.yml file?

No, replace it and try if this works.
