ValueError: Buffer dtype mismatch, expected 'long' but got 'long long'

Hi,

I am trying to run this on Windows CPU Machine.

Executed python generate.py configs/demo/demo_combined.yaml but getting below error -

=> Loading checkpoint from url...

    cdef long[:, :] points_view = points_np
ValueError: Buffer dtype mismatch, expected 'long' but got 'long long'

I tried changing

points_np = np.zeros((points.size(), 3), dtype=np.int64)

to

points_np = np.zeros((points.size(), 3), dtype=np.int32)

and

points_np = np.zeros((points.size(), 3), dtype=np.int32_t)

But no luck.

Could you please help me.

Hi @jay-thakur , thanks a lot for your interest in our project!

I am sorry but we only tested the code on Linux GPU machines. I do not have access to Windows machines, so I sadly I cannot help you here. Good luck!
