Thanks for the report. Please could you provide more information about what caused this problem:
Thanks. |

I've built the referenced https://github.com/kieferk/pymssa and run this: import numpy as np
from pymssa import MSSA
mssa = MSSA(n_components=None,
window_size=None,
verbose=True)
mssa.fit(np.arange(100.))with Numba 0.43.1, worked as expected. Closing this issue due to lack of information. If more information becomes available please add it and reopen the issue. Thanks. |

I've run the same code with Numba 0.44.0, but also raised a error. |
|
I've run into the same issue as @veager . I'm running Windows 10 64bit and I've downloaded the latest 64bit Anaconda distribution (version 2019.03). Then I installed pymssa with this command: I noticed that the code that @stuartarchibald posted works in a Google colab environment, so for the meanwhile, I've been working there. |
|
I have got the same issue, also working with 64bit Anaconda distribution. |
|
I suspect the problem is to do with integer sizes on windows. |
Hi, I managed to get the code to work by commenting the @jit decorator above the function in the line 217 of the optimized.py file, as below: #@jit(nopython=True, fastmath=True) --> Comment this line |

This should not have happened, a problem has occurred in Numba's internals.
