@romainl The note says it is closed because This question does not appear to be about a specific programming problem, a software algorithm, or software tools primarily used by programmers.. It is exactly about about a specific...software tool primarily used by programmers. I am asking if others encountered this issue, and if so, how it can be solved. — Magnus 33 secs ago

Library and software recommendations are off-topic and disallowed here, so your question will probably be closed. Your best bets are to either try to make it work with the MicroPython port of numpy, rewrite the C to work with MicroPython (which is written in C), or do the calculations on a server and request them to be done via an API. In any event you're going to need to do a substantial amount of work yourself. — romkey 29 secs ago
