Hi Nnamdi,
Thank you for providing the information. The Windows conda build for
PyChrono is having know issues recently. We are aware of that and it's
expected to be fixed within the week. If you are in urgent need of
PyChrono, I suggest you build from scratch using cmake (Method A) or use
PyChrono's conda distribution on Linux.
I will keep you posted once the issue in the Windows conda distribution
is fixed.
Best,
Bocheng Zou

Hello Bocheng,
Thank you for reply.
I installed PyChrono via method C. PyChrono through Conda (ref:

For the last step I installed via conda install
pychrono-9.0.1-py310_5372.tar.bz2

Hi Nnamdi,
Thank you for reaching out. I'm Bocheng and I'm a UW-Madison
student responsible for PyChrono distributions. Could you please
clarify the specific way you install the PyChrono? We currently
support three ways of installation on Windows.
A. Build from scratch using cmake (ref:

B. Precompiled binaries for Windows (ref:

C. PyChrono through Conda (ref:

Could you please specify the way you install the chrono? This will
be helpful for us to investigate the issue further.

Hello,
I have recently been faced with an error whenever I try to run
any Python programs in PyChrono. Has anyone encountered this
before? I use Visual Studio Code and Pychrono 9.0.1 on a Windows
PC. I followed all the steps for installing Pychrono in a virtual
environment. I have tried uninstalling and reinstalling, but it
hasn't helped. Everything worked fine in the same env, this error
just appeared suddenly. Please, I would like some advice on this.
Best regards
