[karongsama]

Hi,malcolmw.
When I use ur pykonal package,I always get the ERROR that says 'could not get source code'.And I also get the ValueERROR which says 'Buffer dtype mismatch, expected 'Py_ssize_t' but got 'long' '.
I dont understand why I just copy your code and try to run but failed.
I've try to download the past version but still failed
I wonder if my computer went wrong or something get wrong.
Please help me
Thanks

Hi @karongsama, Can you please tell me about your environment such as you OS and versions of Python and cython?

[karongsama]

i use windows and 3.10.9python,0.29.33Cython
i think thats my environment problem because when i use online server it can run as i expected
maybe its better to use 3.8 python or there is some packages conflict with pykonal
or just Cython has something wrong because the type Py_ssize_t
Thanks for ur help!

Hi @karongsama, unfortunately I have encountered this problem before on Windows and was unable to debug it in platform-independent way, so I am unable to support Windows users at this time. Do you have access to a Linux machine you can work on?
