Error when installing on fresh conda env and apple macos silicon m1

[scalastic]

Hi,

On an apple m1, I made sure to install tensorflow 2.7 on a new conda virtual environment:

% conda install -c apple tensorflow-deps==2.7.0
% pip install tensorflow-macos==2.7.0
% pip install tensorflow-metal 

But when I tried pip install nebullvm I get this error:

ERROR: Cannot install nebullvm==0.1.0, nebullvm==0.1.1, nebullvm==0.1.2, nebullvm==0.2.0, nebullvm==0.2.1 and nebullvm==0.2.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    nebullvm 0.2.2 depends on tensorflow<2.8.0 and >=2.7.0
    nebullvm 0.2.1 depends on tensorflow<2.8.0 and >=2.7.0
    nebullvm 0.2.0 depends on tensorflow<2.8.0 and >=2.7.0
    nebullvm 0.1.2 depends on tensorflow<2.8.0 and >=2.7.0
    nebullvm 0.1.1 depends on tensorflow>=2.7.0
    nebullvm 0.1.0 depends on tensorflow~=2.7.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

What am I missing ?
Thanks

Hello @scalastic! Try installing nebullvm using

pip install nebullvm==0.2.2

I will try to investigate the behavior further and correct it before the next release.

Looks like nebullvm is not finding any valid tensorflow installation. Which conda version are you using? On MacM1 I usually use mini-forge where I can simply install tensorflow running

conda install tensorflow

After installing tensorflow you can proceed with the installation of nebullvm

[scalastic]

I'm using mini-forge also but I've installed tensorflow-macos, the one from Apple. It seems not to be recognized as tensorflow as it's named tensorflow-macos...

When I now execute conda install tensorflow, it offers me to install tensorflow (once again).
And nebullvm is installing now !

Ok, that was the point: I thought I could benefit from both worlds, the Apple's version of Tensorflow and Nebullvm...
Why not after all ?
