"guided_scatter_maps_kernel" not implemented for 'Bool'

[gafniguy]

Hi,

I'm trying to run any of the demo scripts and getting this error from the CUDA section. It is running on a fresh conda environment configured with the requirements file with CUDA 10. Any idea?

Thanks for making the project available.

I get the exact same error, with cuda 10.

I run into the same error too. (I'm using CUDA 10.0; also tried with CUDA 9.2, if it helps).

I got around the error by adding a line here
https://github.com/yifita/DSS/blob/master/DSS/core/renderer.py#L881

I cast occludedMap to float() by adding a line just below the line referenced above

occludedMap = occludedMap.float()

However, I don't know if that should indeed be the fix. Maybe @yifita can comment.

This is an issue due to a breaking change in pytorch 1.2.0. Boolean is no longer interpreted as uint8.
The solution posted by @krrish94 works. On the other hand, one can also change the map to uint8.

I've updated the requirements.txt so that now pytorch 1.1.0 should be used.
This should fix this compatibility issue.
