Any update on this? (I'm having a similar problem)

It would be nice if we received a warning!

@Frameworks Engineer: any update on this?

This also worked for me! Could you please explain how did you get to the working combination python3.9.1 and python -m pip install tensorflow-macos --no-cache-dir?

This doesn't work for me. Created fresh conda environment, then conda install -c apple tensorflow-deps==2.5.0, then when python -m pip install tensorflow-macosgot the same error (this is just the final part of the errors): Traceback (most recent call last): File "/private/var/folders/0k/hz9yngm56nz1htdc3c3t3d0c0000gn/T/pip-install-25u3hpzs/grpcio_14e511c33ab9483dbc8eb10bd70d4a4b/src/python/grpcio/commands.py", line 285, in build_extensions build_ext.build_ext.build_extensions(self) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/command/build_ext.py", line 449, in build_extensions self._build_extensions_serial() File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/command/build_ext.py", line 474, in _build_extensions_serial self.build_extension(ext) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/site-packages/setuptools/command/build_ext.py", line 203, in build_extension if ext._needs_stub: AttributeError: 'Extension' object has no attribute '_needs_stub' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<string>", line 1, in <module> File "/private/var/folders/0k/hz9yngm56nz1htdc3c3t3d0c0000gn/T/pip-install-25u3hpzs/grpcio_14e511c33ab9483dbc8eb10bd70d4a4b/setup.py", line 525, in <module> setuptools.setup( File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/site-packages/setuptools/__init__.py", line 153, in setup return distutils.core.setup(**attrs) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/core.py", line 148, in setup dist.run_commands() File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/dist.py", line 966, in run_commands self.run_command(cmd) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/dist.py", line 985, in run_command cmd_obj.run() File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/site-packages/setuptools/command/install.py", line 61, in run return orig.install.run(self) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/command/install.py", line 546, in run self.run_command('build') File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/dist.py", line 985, in run_command cmd_obj.run() File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/command/build.py", line 135, in run self.run_command(cmd_name) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/dist.py", line 985, in run_command cmd_obj.run() File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/site-packages/setuptools/command/build_ext.py", line 79, in run _build_ext.run(self) File "/Users/machine/miniforge3/envs/tfdeps250/lib/python3.9/distutils/command/build_ext.py", line 340, in run self.build_extensions() File "/private/var/folders/0k/hz9yngm56nz1htdc3c3t3d0c0000gn/T/pip-install-25u3hpzs/grpcio_14e511c33ab9483dbc8eb10bd70d4a4b/src/python/grpcio/commands.py", line 288, in build_extensions support.diagnose_build_ext_error(self, error, formatted_exception) File "/private/var/folders/0k/hz9yngm56nz1htdc3c3t3d0c0000gn/T/pip-install-25u3hpzs/grpcio_14e511c33ab9483dbc8eb10bd70d4a4b/src/python/grpcio/support.py", line 117, in diagnose_build_ext_error diagnostic(build_ext, error) File "/private/var/folders/0k/hz9yngm56nz1htdc3c3t3d0c0000gn/T/pip-install-25u3hpzs/grpcio_14e511c33ab9483dbc8eb10bd70d4a4b/src/python/grpcio/support.py", line 96, in diagnose_attribute_error raise commands.CommandError( commands.CommandError: We expect a missing `_needs_stub` attribute from older versions of setuptools.

I'm already using macOS 12.0 Beta 8

Any way to make this work inside a Conda environment?
