Hi there,
Looks like python packages compatibility broke when you tried to downgrade to tensorflow-deps==2.5. I would suggest creating a new conda environment and following the install steps to get the latest TensorFlow (instructions) or see commands (option #2) to install TensorFlow 2.5. If you don't specify any versions, you'll get all the latest versions by default (currently these are tensorflow-deps==2.6, tensorflow-macos==2.6, tensorflow-metal==0.2.0), which is recommended to use with macOS 12.0+ (How to update to the latest available macOS here)
To be able to use older versions, please be specific during the install:
conda install -c apple tensorflow-deps==2.5.0
python -m pip install tensorflow-macos==2.5.0
python -m pip install tensorflow-metal==0.1.2
Hope that helps!
