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.

It solved the issue, thank you for the very quick answer!
