OVITO python module installation

Hello good people,
I have been trying to install ovito python module using

conda install --strict-channel-priority -c https://conda.ovito.org -c conda-forge ovito=3.10.2

But I am getting this error:

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 500 INTERNAL SERVER ERROR for url https://conda.ovito.org/linux-ppc64le/current_repodata.json
Elapsed: 00:07.371748

A remote server error occurred when trying to retrieve this URL.

A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request. The problem may be spurious, and will resolve itself if you
try your request again. If the problem persists, consider notifying the maintainer
of the remote server.

I think I have been seeing this error for sometime now. Any suggestions? Thanks.


It looks like this error was due to a web server configuration problem, which needed to be solved on our end. The web server hosting the conda channel was responding with http redirects instead of code 404 to non-existing URL requests, which made the conda install command fail.

This problem should be solved now, please try again.

However, it seems you were trying to install Ovito on a Linux machine with ppc64le architecture. Is that correct? This will not work in any case, because we currently don’t provide builds for this processor type - only x86_64.

Thanks for resolving the issue. It’s working now.

And yes, that particular machine is on a ppc64 architecture. I am switching to a x86_64 machine now. Thanks again.


I am also having same issue with Apple Silicon.

Even after succesful installation I could not import ovito.

Could you please attach the output of the conda list command? I would like to see how your conda environment looks like after installation of the ovito package. I assume you have installed the package now using the conda install command.

Yes I did conda install

You have installed the ovito package from the conda-forge channel in your environment. This package does not provide the ovito Python package, only the desktop app. You need to install the ovito package from conda.ovito.org channel. See the install instructions.

After installation, you should see this in the output of conda list (note the 4th column):

ovito        3.10.2          py311h9a57886_1    https://conda.ovito.org

I think new ovito==3.10.2 does not supports python==3.12. So downgrade python to 3.11 and install ovito, worked for me.

Right, we don’t have a Python 3.12 version of the ovito conda package yet. We will be able to provide it once conda-forge has completed the migration to Python 3.12.
