PackagesNotFoundError: The following packages are not available from current channels: - osim Current channels:

This error message indicates that the "osim" package you are trying to install is not available in the channels that your package manager is currently searching.

There are a few things you can try to resolve this issue:

1. Check if you have spelled the package name correctly. Sometimes, typos can cause this error.

2. Try adding additional channels or repositories to your package manager's search list. You can do this by running the following command:

conda config --add channels <channel_name>

Replace <channel_name> with the name of the channel that contains the "osim" package.

3. If the package is not available through conda, try installing it using pip:

pip install osim

Note that this will only work if you have pip installed on your system.
