The installation doesn't work in conda.

[OwenHua666]

conda create –-name synsin_env –-file requirements.txt gives the error: CondaValueError: The target prefix is the base prefix. Aborting.
I tried to install the required libs using virtual environment, but import quaternion fails and pytorch3d also report an error.

Hey @OwenHua666,

You need to install pytorch3d from the pytorch3d-nightly conda channel.

I had the same issue, and ended up creating a separated 'clean' environment.yml with all the dependencies : https://github.com/ilnmtlbnm/synsin/blob/master/environment.yml

You can just conda env create -f environment.yml then conda activate synsin_env and you're all set.

Don't forget to bash download_models.sh, the demos will work, from there you can start to dig deeper.

Thanks for the help @ilnmtlbnm ! Hope that fixes your problem @OwenHua666

[OwenHua666]

I will try and let you guys know. Thanks a lot!

I had the same issue and can confirm that this helped. Thank you! 😊

Closing this issue as everything seems to be resolved. Feel free to re-open if anything new emerges.
