Anaconda - dmsh installation problem #93

Closed griff10000 closed 1 year ago

griff10000 commented 2 years ago

I have a new machine with Windows 11 and have installed Anaconda3-2021.11-Windows-x86_64.

Tried running in powershell window: conda install dmsh Not found.

Tried: pip install dmsh This installed dmsh.

But get following error when running a simple dmsh application that ran on my old Windows 10 machine:

ImportError: cannot import name 'NDArray' from 'numpy.typing' (C:\Users\Graham\anaconda3\lib\site-packages\numpy\typing\__init__.py)

The installed numpy version = 1.20.3

I second that, some of my students had the issue during a practical and I ended up generating the mesh on my machine and sending them the arrays.

Windows 10, anaconda and numpy 1.20.X

From memory ... After, pip install dmsh To get the new dmesh to work on Windows 11 and anaconda, I had to remove my existing numpy version and then re-install version 1.22.2 Hope this works.
