tests fail with cython optimization

Question

tests fail with cython optimization

francispoulin opened this issue 4 years ago · comments

I can happily say that all the tests pass without any optimization. Today I tried with cython and numba.

The good news is that with numba they all pass.

The bad news is that with cython I have 202 fail. This is both on my laptop and a computer cluster, but both are installed using conda so it's really the same system.

I will continue to use numba but wanted to point this out, in case you weren't aware of it already.

I did not know. Which tests fail?

Below is the list that I get.

P.S. Is there a simple way to do bulk indenting in github?

Hi,
FYI: I am currently running the tests from the conda package and test_tensorproductspace.py fails.

python test_tensorproductspace.py
Traceback (most recent call last):
  File "test_tensorproductspace.py", line 707, in <module>
    test_eval_tensor('d', 1, lbases.ShenBiPolar0Basis, 'LG')

    result = fft.eval(points, u_hat, method=0)

    assert i < self.N-3
AssertionError

I do know if this error is related to an outdated conda package or if it does not occur if the current github-Version is used.

Best,
Sebastian
