Installation error

[Wenbo-Duan]

Hi,

I’m a new user of TCRM on windows and I’m running into an error when installing the package and running the run_test_all.cmd (shown below). I'm using python 3.8.8 on windows 10 enterprise version. I'm also a bit confused by the instruction for Setting the environment for windows. What exactly needs to be set up? Is it PYTHONPATH?

Any input would be appreciated, thanks!

Hi @Wenbo-Duan Setting PYTHONPATH is essential to point to appropriate python libraries. If you're executing TCRM at a Windows command prompt, then you need to use the set command for this. I have the code installed on my local machine in C:\WorkSpace\tcrm, so I need the following to add the TCRM modules to the path:

set PYTHONPATH=%PYTHONPATH%;C:\WorkSpace\tcrm;C:\WorkSpace\tcrm\Utilities

If you have your other python libraries (e.g. matplotlib) installed in a non-standard directory, then you will need to add those directories to the PYTHONPATH as well.

Thanks, I'm using anaconda PowerShell prompt and I set PYTHONPATH using the following command: conda env config vars set PYTHONPATH=%PYTHONPATH%;C:\TCRM;C:\TCRM\Utilities When running the test command, I get the following errors, all of them seem to be related to the color map. Can I ignore this error?

Thanks!

Seems that assertDictEqual doesn't like anything other than really simple dicts. The dicts in the colormaps are comprised of numpy arrays as values, and this results in the observed ValueError. I've updated the test suite to compare individual elements of the colormaps, so as to avoid using assertDictEqual.

See https://github.com/GeoscienceAustralia/tcrm/commit/091db2f503f9ad1a5c45ac3306a21eae73d8ea8a
