Hi! I am installing LASIF following the instructions on http://lasif.net/prerequisites.html
Everything went well until testing LASIF by executing py.test in the toplevel LASIF directory.

I got the following errors:

The package version I am using:
Python 3.7.6
numpy 1.18.5
scipy 1.4.1

How can I install LASIF correctly in Python 3.7.6 ?

HI~ Here are three errors showing up when I run 'py.test':

Respected Lion Krischer：
When I execute py.test ,I got the same result as you（）, indicating that my LASIF program was installed correctly.

The First Question:When i using lasif launch_model_gui, the images I get from your tutorial can only show part of the images.In the physical domain, data information is displayed only in the Mediterranean Sea, but not on European land. Why?
The Last Question:When I use the script that you update the model, although I adjust the script according to my own file, there is a problem that can not run. How can I solve it?

If you can get your help, we would be very grateful！！！

There is an error when I run py.test after the installation.

There might be some problem during my installation.
Could you please suggest me how to solve it?
Thank you so much.
