Regression Tests - Ubuntu in Windows 10

[bmazetto]

Hello Everyone,

I’m facing some failures during the Regression Tests and problems to get the plots.

Bug description
No plots of failed cases.

To Reproduce
Basically, I used a similar procedure as the one from #384 to build OpenFAST in Ubuntu and the same steps shown in https://raf-openfast.readthedocs.io/en/docs-general_updates/source/testing/regression_test.html to run the Regression Tests.

I have installed matplotlib using “sudo apt-get python3-matplotlib”. Numpy is installed, as well.

Expected behavior
I tried to generate the plots using the given python routine, so I could compare my results to the baseline. I expected to I go to the directory “openfast\build\reg_tests\glue-codes\openfast” and access the “regression_test_summary.html”, where I could see the plots for the failed cases.

Screenshots
These are the results from the Regression Tests executing with CTEST:

These are the results executing the Python routine just to generate the plots, without running the cases again:

Additional context
A little time ago, I manage to build OpenFAST in Windows using Cygwin. Now, I'm running my simulations using it. However, since I have a great number of scenarios to run and they are taking a lot of time, I'd like to run them in parallel. To do so, I've installed Ubuntu for Windows 10 in the same computer and used a similar procedure mentioned in #384 to build OpenFAST in Ubuntu.

Is there a better way to run OpenFAST simulations in parallel using only one notebook? Could someone give me a suggestion?

Thanks a lot for your time!

@bmazetto The documentation link you've included above is my fork's documentation which is just something I use for development. It is severely out of date. The official OpenFAST documentation is linked at the top of the GitHub page and here's the link. That being said, you simply need to install Bokeh at version 1.4 instead of matplotlib.

As for running in parallel, try running with ctest instead of with the Python driver. For what its worth, we are working on improving the custom Python infrastructure so that running in parallel will be supported.

Hello @rafmudaf , thank you for your help. Now I'm getting the plots. I had to change from Bokeh 2.0.2 to 1.4.0.

I'm not sure how to use the CTEST to run my own simulations. Could you provide an example of how to do it? Maybe point out which files I should customize.

Read the CTest section of the documentation here. Let me know if some part of that is lacking or not clear.
