Users creating conda environments
may encounter an I/O bug on Cheyenne and Casper when using Python versions 3.8 or later, so CISL recommends specifying Python 3.7 unless a new version is needed. Users encountering the bug receive an error message saying “BlockingIOError: [Errno 11] Resource temporarily unavailable.”
Specifying Python 3.7 or an earlier version will avoid the problem. When creating a new conda environment, specify the Python version as 3.7 as follows:
conda create --name my_conda_env python=3.7
CISL will advise users when it is no longer an issue.
