Numpy 1.24.2 fails the pyTFM add-on

[alexlib]

One of the files in the older openpiv version you use has np.float and this fails with the new numpy > 1.24

one workaround we found was to uninstall the default numpy and reinstall it

pip uninstall numpy
pip install numpy"<1.24"

A better solution is to update your use to a more recent version of openpiv-python which resolved this problem long ago.
