Error Training with Hashtable #96

Closed zenos4mbu closed 1 year ago

zenos4mbu commented 1 year ago

Hi thank you for the awsome work!

Using Hashgrid for the fox scene from [Instant-NGP] repository with the new version of the app scripts returns me this error

error

Seem a problem with the conversion from half to float.

Thank you again

Hi @zenos4mbu ! Can you please re-run python setup.py develop? Our recent changes optimize the CUDA code which runs the HashTable to take advantage of half precision. If you pulled it, it would require rebuilding.
