PyAMG Error

[49takashi]

Hi,

I am trying to use SU2-pyamg on the server and got some errors. Let me ask some questions.
My issue is related to that in the #948. Actually, I am in the situation very similar to https://github.com/su2code/SU2/issues/948#issuecomment-619332650 :

Traceback (most recent call last):
  File "/dfs/user/takashi279/miniconda3/envs/temp_su5/bin/mesh_adaptation_amg.py", line 38, in <module>
    import SU2
  File "/dfs/user/takashi279/miniconda3/envs/temp_su5/bin/SU2/__init__.py", line 14, in <module>
    from SU2 import amginria
  File "/dfs/user/takashi279/miniconda3/envs/temp_su5/bin/SU2/amginria/__init__.py", line 4, in <module>
    from .interface import *
  File "/dfs/user/takashi279/miniconda3/envs/temp_su5/bin/SU2/amginria/interface.py", line 41, in <module>
    import _amgio as amgio
ModuleNotFoundError: No module named '_amgio'

and followed the instructions provided as in https://github.com/su2code/SU2/issues/948#issuecomment-619334494:

The _amgio extension should be built by default. I haven't had any issues on any of the machines I've built on, so I appreciate the feedback.

Just curious, are you running with python >=3.7? The shebang in all the SU2 python scripts

#!/usr/bin/env python

uses whatever python is set to in your environment variables, but pyamg/_amgio will only build/run with python >=3.7. Could you also check if the _amgio extension was installed in your site-packages (probably located in ~/.local/lib/python3.x/site-packages)?

If it didn't build/install, you could go into extensions/AMGIO/su2io and run

python3 setup.py build_ext && python3 setup.py install

If it did build/install, try the command

python3 $SU2_RUN/mesh_adaptation_amg.py -f invCyl.cfg -n 6

After doing python3 setup.py build_ext && python3 setup.py install, I encountered the following error:

(temp_su5) takashi279@turing1:/dfs/user/takashi279/plasma/design/multiscale_adap3/SU2/externals/AMGIO/su2io$ python3 setup.py build_ext && python3 setup.py install

Am I missing any dependencies? I previously compiled SU2 feature_adap branch without issues, and have already installed pyAMG. My python version is 3.7.12.
Any help would be really appreciated.
