Installing on Mac OS 11.5.2

fedefalo commented 3 years ago

Hi. I'm trying to install pygmo through conda as instructed. When I run import pygmo pygmo.test.run_test_suite() the test suite finds different errors. What can I do to fix it?

Could you post here the full screen output of the test suite?

fedefalo commented 3 years ago

Sorry, it is a bit long

bluescarni commented 3 years ago

@fedefalo I am a bit confused because from the screen output it seems like the test suite is being run multiple times (there's a lot of repetition in the output). Are you trying to execute the test suite in some sort of multiprocessing environment?

fedefalo commented 3 years ago

@bluescarni No, I'm just running the two-lines script as suggested in the documentation. I don't know why the test suite runs multiple times. In fact I have to manually interrupt the process because it loops.

bluescarni commented 3 years ago

@fedefalo are you running the test suite from an interactive Python session? If so, could you try to run this command from your terminal instead:

python -c "import pygmo; pygmo.test.run_test_suite(1); pygmo.mp_island.shutdown_pool(); pygmo.mp_bfe.shutdown_pool()"
