I’m also working on a mac running BigSur at the moment, and get Cython related errors when i try
brian2.test()
under the section
Running tests for target cython
I get about 90% F as in failed.
I tried marcel’s suggestion of uninstalling and installing the Brian2==2.4.2.post0.dev149 development version. Unfortunately, this didn’t fix the cython issue for me, and seemed to generate a single extra error under the numpy codegen section. This is what the error summary looked like:
**226 failed** , 24 passed, 8 skipped, 414 deselected in 380.99s (0:06:20)
ERROR: 2/4 test suite(s) did not complete successfully (see above).
let me know if there’s any other test outputs that would be useful and whether it would be useful for me to file this as an issue on github
