Conda installers available!

I did get the same thing on windows with a different CUDA version but only when I forgot to add the coda-forge channel. Ngsolve has a lot of dependencies that can only be matched in this channel so the short version of supplying only the ngsolve channel in the install command does not work.

So if you setup a new environment just do (strict priority might not be needed under windows):

conda config --env --add channels conda-forge
conda config --env --add channels ngsolve
conda config --env --set channel_priority strict
conda install ngsolve

Best,

Thanks! I used you way, and I could install the package. However, when I run , I got
I gave up, and used .msi to install on windows. It worked now.

Im getting this same error, did you ever work it out?

Hi there, I am trying to install Netgen on my MacBook. I tried the DMG file but ran into an error with it not finding python etc. I now tried the anaconda approach and the install produces pages and pages of errors with "conflicts"... Here is some of the terminal code/output. I have installed the latest anaconda distribution.

~ % conda install ngsolve

**Issue Resolved by upgrading my Ubuntu version.**
Hello Matthias,

I have been using Netgen/NGSolve on 64-bit Ubuntu 16.04 LTS for the past 6 months. I installed it using Conda.
Only recently have I encountered the following error
NameError: name 'dx' is not defined

with codes involving dx.
I followed the advice on: Can not run navierstokes.py example
( ngsolve.org/forum/ngspy-forum/903-can-no...okes-py-example#2046 )
but in vain.
More info on my install:
# packages in environment at /home/nssharma/anaconda2/envs/ngsolve_test:
netgen 6.2.2006 py37he358ceb_3 conda-forge
ngsolve 6.2.2006.post48 py37_0 ngsolve

Could you please tell me what I can do to fix this NameError?

Many thanks!
Natasha

I have tried installing using the conda packages on multiple systems and when it attempt to run:

jupyter nbextension install --user --py ngsolve

i get an error similar to

FileNotFoundError: [Errno 2] No such file or directory: '/home/username/anaconda3/envs/ngs/lib/python3.8/site-packages/ngsolve/nbextension/static'

Can anyone provide a fix to this?
