[Bug]: starting error message when importing SpectroChemPy on OSX terminal+ipython and python

[fernandezc]

What happened?

while there is no problem under Jupiter lab, when using OSX terminal+ipython to run spectrochempy, I get this error:

Under terminal+python shell, I get this one:

These errors, do not block the use of SpectroChempy but are quite annoying.

What did you expect to happen?
