Example not working: Error: No module named 'pyhams'

[HansiLeMann]

I have recently rebooted my PC and reinstalled RAFT. However, the installation seems to be unsuccessful as when I run the example_from_yaml.py i get the following error:

cd RAFT cd examples (raft-env) PS C:\Users\hfleh\RAFT\examples> python example_from_yaml.py Traceback (most recent call last): File "C:\Users\hfleh\RAFT\examples\example_from_yaml.py", line 6, in import raft File "c:\users\hfleh\raft\raft__init__.py", line 3, in import raft.raft_model as model File "c:\users\hfleh\raft\raft\raft_model.py", line 15, in import raft.raft_fowt as fowt File "c:\users\hfleh\raft\raft\raft_fowt.py", line 7, in import pyhams.pyhams as ph ModuleNotFoundError: No module named 'pyhams' (raft-env) PS C:\Users\hfleh\RAFT\examples>`

I have cloned and setup all relevant repositories: WISDEM, MoorPy, PyHAMS, RAFT. Can you help me?

[gbarter]

The pyHAMS installation did not succeed. There should be a setup.log and a compile.log file in the meson_build directory in your pyHAMS directory. Can you post those?

[HansiLeMann]

Thank you for the very fast response!

I got the pyHAMS installation working, but now WISDEM is failing. Seems to be an installation error again.

When I install WISDEM the output is as follows:

It is likely that installing chardet package will help f2py determine the input file encoding correctly.

When I run the example_from_yaml I get the following error:

Do you have any recommendations of what to do?

[gbarter]

Yes, I just fixed this the past few days. There were changes in the 3rd party libraries that made them a little less robust. If you do:

git checkout develop
git pull
python setup.py develop

In your WISDEM directory, things should be working.

If you instead installed WISDEM as a conda package, then I can push an update there, but haven't done so yet.

[HansiLeMann]

Thank you! I got WISDEM successfully downloaded, but now errors, when running the example_from_yaml:

I have made sure to install the necessary libraries. Do you have any suggestions?

[gbarter]

Since this is a bug in the core RAFT code, I will defer to @mattEhall here before making any code edits.

[vbenifla]

Hello,

I believe this is due to numpy's latest release 1.24. For now one could use an older version of numpy, I downgraded it using: conda install -c conda-forge numpy=1.23

And now the Raft example from yaml works fine. Hope it helps !

[HansiLeMann]

Thank you! It's working.

[mattEhall]

Thank you all, for the problems and solutions. I've just pushed a small fix for that last bug (now using float() instead of np.float()). There is also has a small update to allow using CCBlade without the full WISDEM installation (as discussed in https://github.com/WISDEM/RAFT/issues/17).

[gbarter]

I submitted some robustness improvements in the install of both pyHAMS and WISDEM. If the primary purpose is to use RAFT, I would suggest simply doing conda install wisdem to satisfy dependencies. The alternative is to go through the WISDEM installation steps outlined at its Github site.
