Problems with Numpy 1.24.0

[florentLutz]

Describe the bug The solution for compatibility between OpenMDAO and Numpy 1.24.0 (https://github.com/OpenMDAO/OpenMDAO/issues/2737) has not been integrated in a release yet creating issues on new installs of FAST-OAD and its plugins.

Fix A quick fix is to downgrade the version of numpy to anything below 1.24.0

What is the concerned OpenMDAO version in your tests? I realize OpenMDAO 3.23 got released on the 10th of January, and is advertised as getting along with numpy 1.24.

If your test is with OpenMDAO 3.23, we will have to look deeper into that problem...

I managed to replicate the bug on the Binder and sure enough, the version of OpenMDAO was 3.21.0. I tried upgrading to 3.23.0 and the issue disapeared (didn't check further). However, when upgrading to the 3.23.0 I got the following message:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
fast-oad-core 1.4.1 requires openmdao<=3.21,>=3.10, but you have openmdao 3.23.0 which is incompatible.

Which might explains why it didn't install the latest version of OpenMDAO

Looks like there is no more problem when last versions of numpy and openMDAO are installed.
