Hi Nnamdi, I hope you're doing well. We're excited to share that we've refactored the Conda build pipeline and released updated distributions of PyChrono with improved cross-platform compatibility, which is likely to resolve the issue you encountered. To try out the latest release, please create a new environment and run the following commands (note that the installation command on the website is now oudated):
conda create -n chrono_test python=3.12 -c conda-forge conda install pychrono -c projectchrono -c dlr-sc -c conda-forge Please let us know if there are any remaining issues.

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 On 7/31/25 00:45, 'Nnamdi Chikere' via ProjectChrono wrote: Hello Bocheng, Thank you for reply.

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.
