Re: Conda OpenSim slow on Linux

Okay I think I got it: - On Windows, the opensim conda package is shipped with mkl, mkl_fft, mkl_random - On Linux, mkl_fft and mkl_random are removed, it installs nomkl, libopenblas, openblas instead (numpy is also downgraded) However, it does not seem like OpenBLAS accelerates linear algebra as mu...

Re: Conda OpenSim slow on Linux

I'm just remembering something that could be of significant importance: I first could not run OpenSim IK, as it made Python crash with this error: Intel MKL FATAL ERROR: Cannot load libmkl_avx.so or libmkl_def.so I solver the issue by doing: export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libmkl_def.so:...

Re: Conda OpenSim slow on Linux

Hi Ayman, Thank you for answering! First of all, you're right, I'll try to parallelize IK on my multiple threads, it will run significantly faster. Considering that python 3.8 with OpenSim 4.4.1 and python 3.11.9 with OpenSim 4.5.1 ran at the exact same (slow) speed on my linux system, I would not e...

Conda OpenSim slow on Linux

Hi, I installed the opensim conda package, and I noticed that inverse kinematics is much slower on my Ubuntu server than on my laptop. This is annoying, since I need to process a massive amount of data that I cannot download on my computer. Do you have any idea why, and how to speed it up? Here are ...

Re: pose2sim

Hi, The trc file is probably not found at this address, click on the little blue folder to manually select its correct location. I'm planning to make Pose2Sim work without having to use the OpenSim graphical interface (or just for visual verification), but I'm not sure when I'll find time for it yet...

Re: Failed loading mesh 'file

Thanks, it makes more sense. I followed the issue you just filed. However, I don't think that missing Geometry files would affect the results, would it? Concerning that fs error, does it mean that currently, no trials with a frequency under 60 Hz would work? If so, I don't understand how AddBiomecha...

Re: Failed loading mesh 'file

Same error with a very fast and diverse motion (throwing ball feint, side step and sprint). Only 130 frames though. Is it too short? I see that the cut-off frequency ( lowpass_hz ) is defined as 30. Is it impossible to process data that is sampled below 60 Hz? Or am I missing something? See this iss...

Re: Failed loading mesh 'file

Hi, thank you for your answer and sorry for the long delay. I understand the point about the diversity of the motion. What error would it give if the motion is not diverse enough or too slow? Would this be something like that? TrialPreprocessingError - TrialPreprocessingError: Error encountered when...

Re: EllipsoidJoint in OpenSim vs NimblePhysics

Hello again, I need to choose a full-body OpenSim model and I have potential applications with SMPL meshes, so the BSM model from SKEL felt like the perfect fit. However, there are issues when using it outside of Nimble physics, both in the GUI and the conda package. After converting the ply Geometr...
