OSError: [Errno 36] File name too long when importing dcor

Which version of Numba are you using?

[Quentin62]

I have numba version 0.53.1. I tried with the latest (0.54.1) and I still have the same error.

Unfortunately, Numba uses very long names for the cache files. Also, your filesystem seems to accept less length than others.

The only "solution" I can recommend to you is to use the environment variable NUMBA_CACHE_DIR in order to place the files in a more shallow path and hope that is enough (see https://numba.pydata.org/numba-doc/dev/reference/envvars.html#numba-envvars-caching).

Note also that if your Windows is up-to-date, you may be able to request that longer paths are accepted:

I suppose you solved your problem, so I will close this issue. Please reopen it if the problem persists.
