When running JupyterFlow from Designer, everything works. But when running it from Server, I get this error:

 

  File "C:\Users\service-account\.shiv\99b9e8838bc10d0-cv-0-1_e20b05ea24484f9870ce408477e8f9e6c142d0c976ea8c102877ed12647d4512\site-packages\zmq\backend\cython\__init__.py", line 6, in <module>

    from . import (

ImportError: DLL load failed while importing error: The specified module could not be found.

This prevents JupyterFlow from working when running on Server.

This issue is caused by a vcruntime140_1, a .dll file that is normally present in the user's system32\ directory, being missing. For many users, that .dll is not missing, but for some reason it's not there for others.

 

The solution is to install the latest version of the JupyterFlow yxi (version 0.2), as the .dll has been added as a dependency in that. To find the latest version of JupyterFlow, check out this article.

 

If version 0.2 is not available yet, it should be posted by 24 September, 2021.
