I am not able to replicate the problem... :face_with_spiral_eyes: Still doing some tests

gdurif commented 2 years ago

While doing some tests, I stumbled upon the following problem while running pykeops/test/unit_tests_numpy.py.

Issue with shared library file in C++ mode: pykeops_cpp_xxx.so: file too short

$ python unit_tests_numpy.py
