3 pytest errors

Hi, all

I just installed the swot simulator and run the pytest. Three errors were found:

I also tried this on Windows system and the errors are the same.

Can these error be neglected?

Thanks

If you run the code from a git clone, you have to run the setup.py script to initialize the version.py file. This file is built automatically to deduce the version used by the simulator.

Frédéric BRIOL,
Thanks very much.
I misunderstood the root directory of the swot_simulator repository in the installation instruction. I installed the simulator by conda. But test it in the git repository.
Maybe, the root directory means that in conda environment. Like \miniconda3\Lib\site-packages\swot_simulator.
However, there is no tests in \miniconda3\Lib\site-packages\swot_simulator. I simply copy tests directory from git repository to conda environment and run pytest again. Then everything is ok.

Or, like your comments. Install the swot_simulator from resource by python setup.py install. Then run pytest. It is also works fine.
