[BUG] Bug in obfuscating Numpy 1.22.4

[bramth]

After packing with the following command,

pyarmor pack -e "--hidden-import lxml._elementpath --onefile --clean --upx-dir C:\Users\bram\Projects -y --key XXX --icon myicon.ico" app.py

the following error is thrown when obfuscating Numpy 1.22.4 (it seems):

INFO            env\Lib\site-packages\numpy\core\tests\test_protocols.py -> dist\obf\env\Lib\site-packages\numpy\core\tests\test_protocols.py

Any ideas?

Removing the test on line 2523 of the test_regression.py file seems to work as a temporary solution:

    # def test_frompyfunc_name(self):
    #     # name conversion was failing for python 3 strings
    #     # resulting in the default '?' name. Also test utf-8
    #     # encoding using non-ascii name.
    #     def cassé(x):
    #         return x
    #
    #     f = np.frompyfunc(cassé, 1, 1)
    #     assert str(f) == "<ufunc 'cassé (vectorized)'>"
