utils/export.py in wrong folder and cannot access libraries

[coolkite]

Hi,

While trying to convert the .pt to .ply file using the script in utils/export.py, I encountered a few import related errors.

Traceback (most recent call last):
  File "/home/jovyan/gsgen/utils/export.py", line 2, in <module>

Moving export.py to /gsgen and then installing the plyfile library seemed to fix this issue.

Hi coolkite,

This issue can be solved by setting the PYTHONPATH env var:

export PYTHONPATH="."

or

PYTHONPATH="." python utils/export.py <your_ckpt> --type ply

[heheyas]

You can also finish exporting by:

python -m utils.export

This also works in colab

Moving the export file outside the utils directory into the gsgen folder worked for me.

I run into the first problem too, didn't forget to set the pythonpath.

My command:

PYTHONPATH="." python utils/export.py /mnt/c/Users/Andy
/Documents/gsgen/checkpoints/baby_dragon_with_sunglasses_and_a_red_top_hat/2023-11-05/232556/ckpts/step_14000.pt --ty
pe ply

My result:

Are there any other tips you have?

Using python -m utils.export <your_ckpt> --type <export_type> will solve this problem.

Yes, that worked for me, thanks a lot! Could you also tell me why that is, so I can learn what happened (wrongly) please?

The file typing.py shares the same name with python built-in typing package, the -m flag tells python to load from the current working directory first. You can refer official documentation for details.
