There re two problems: Solcore has so few annotations that it will inevitably fail any attempt to go through mypy, at least for now. Unless all things ellipsometry_annalysis.py depends on are annotated, it won't work.

Besides, even if that is done, neither Matplotlib, Scipy nor Numpy will pass mypy checks anyway because they don't have stud files with proper type annotations! The simplest solution, at least for now, is to create a mypy.ini file in the root repo directory with instructions to ignore those errors:

[mypy]
ignore_missing_imports = True
[mypy-setup]
ignore_errors = True

Still, this will not solve the first problem, which requires Solcore to be properly annotated. Please, feel free to add this mypy.ini file.

Let me know when you are done clicking on request rerview above :)

Many thanks for dealing with this!

added the mypy, where is it request review?

Top right of this PR screen, where it says "Reviwers". Anyway, I'm having a look at it, now.
