由于 termcolor 构建不起作用，Tensorflow 安装 M1 Mac 失败

Question

I have tried to install tensorflow on my M1 Silicon (macOS 12.4) by setting up a new anaconda environment and forcing it to use arm64 builds:

 CONDA_SUBDIR=osx-arm64 conda create -n=NAME python=3.9 -c conda-forge --override-channels

and have then followed the developer instructions to use the M1 GPU:

conda install -c apple tensorflow-deps        
pip3 install tensorflow-macos  

But then I get an error for termcolor:

  Building wheel for termcolor (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

Finishing the installation by adding pip3 install tensorflow-metal and then loading the module tensorflow in the python3 shell produces the following error:

Running pip3 uninstall termcolor and pip3 install termcolor produces the same installation error.

Am I just lost here and there is no functioning M1 Silicon built for termcolor at the moment? Or did I mess up somewhere?

Answer 1

Ok got it. Somehow the issue was with pip:

conda uninstall termcolor
conda install termcolor

solved all issues and tensorflow appears to be working (finger's crossed!)

Note that tensorflow-macos can only be installed via pip at the moment, so I first need to let the pip built of termcolor fail, remove it with conda and then re-install it.
