You can test the new features using the branch: 10_redesign_the_tvm_model

pip install git+https://github.com/eduNEXT/tvm.git@10_redesign_the_tvm_model
tvm install v12.2.0
tvm use v12.2.0
mkdir test && cd test
tvm project init
source .tvm/bin/activate
tutor --version
which tutor
tvmoff

Looks good to me.

I found a small bug, and it is that I can't activate the tvm environment from another folder where the .tvm is not.

We can fix it later :D
