Conda package can't find (or doesn't include) `opensim-cmd` executable

[nickbianco]

Platform: Ubuntu 22.04 (through Windows Subsystem for Linux)
Python version: 3.9
Numpy: 1.20.2

I installed the conda package into my conda environment, and while import opensim loads fine inside a Python interpreter, the opensim-cmd command line tool is notfound. I searched the Anaconda directories and found the OpenSim headers, include files, and Python modules but no opensim-cmd executable or any \bin folder associated with the OpenSim package.

@nickbianco I created a conda package on opensim_admin channel
opensim-4.4-py38np120.tar.bz2
According to 7zip it contains the exe's we need but it's not clear where it ends in an actual conda environment. Can you give that a spin? Thank you. You may have to download and install from file in case conda doesn't resolve to this package based on other dependencies. I didn't build all variants pending your feedback.

[nickbianco]

Great, I'll give it a shot! Do you have a Python 3.9 build? I could test the change directly in my AddBiomechanics environment which needs the opensim-cmd executable.

[nickbianco]

Oh, wait. I can just pull down whatever I need from opensim_admin, I think?

[aymanhab]

True but I only built/uploaded the 3.8 variant, I can do 3.9 in less than an hour.

Okay, sounds good. I'll give the py38 version a try now.

[nickbianco]

Looks like it worked! The opensim-cmd executable appears under <anaconda_folder>envs\<env_name>\Library\bin.

I had to install the package using the tar file you posted, installing from the opensim_admin channel failed on Ubuntu. But it seems like that's because the build you created was for Windows (i.e., the executables all have .exe extensions)?

[aymanhab]

Perfect, I'm building 3.7, 3.8 and 3.9 and will upload later today. We'll do the remaining platforms on ci if possible.

[aymanhab]

Windows 3.9 package is now up if still needed, while the others are still building. All packages will be on the opensim_admin channel before moving to the public opensim-org channel.

[nickbianco]

I'll need the Linux package for my workflow. Once that's done building I can test it out.

@nickbianco I'm having problems building on linux because of an internal compiler error building Moco Examples, are you familiar with this? or can we disable building these examples by setting flags in CMake since we're not building Moco anyway for this package? Thank you

@AlbertoCasasOrtiz Thanks for the docker container, it worked great, I'm using it to build a variant that includes the utilities but running into the issue above, have you seen this during testing the container? Thank you

[nickbianco]

I haven't seen this error, but it could be that the Docker container is running out of memory. If simply increasing the memory doesn't work, then yes, let's just disable building the examples until we plan to include the Moco libraries.

[aymanhab]

ok, give it a try when you have a chance, both 3.7, 3.8, 3.9 pkgs for llinux are now on the opensim_admin channel.

[nickbianco]

That worked! The exectuable appears and works as expected when I activate the conda environment it is in.

[AlbertoCasasOrtiz]

@aymanhab As @nickbianco said, the error:

3445.6 x86_64-conda-linux-gnu-c++: internal compiler error: Killed (program cc1plus)

Normally appears when the docker container is out of memory. Another way of bypassing it is by decreasing the number of jobs in the script.
