Error when running. Possible version error with pytorch_lightning

[josemonsalve2]

Hi,

I am having issues running this project. I suspect it's an issue with the version of pytorch_lightning.

Here's the output:

> python3 -m run --ginc configs/nerf/blender.gin
Traceback (most recent call last):
  File "!/anaconda3/envs/nerf_factory/lib/python3.8/runpy.py", line 194, in _run_module_as_main

ImportError: cannot import name 'DDPPlugin' from 'pytorch_lightning.plugins' (~/anaconda3/envs/nerf_factory/lib/python3.8/site-packages/pytorch_lightning/plugins/__init__.py)

System:

I'm running on a Mac studio with MacOS Ventura 13.3.1.

Here are the versions installed by pip -r requirements.txt:

Possible temporary solution

Use pytorch_lightning==1.9.5 in requirements.txt

I have same issue!

After I change my pytorch_lightning==1.9.5, then 'BatchSampler' error occurs.
Last part of the error message is as follows.

In call to configurable 'run' (<function run at 0x7f7fb3ef59d0>)
    dataloader = _update_dataloader(dataloader, sampler, mode=mode)
  File "/compuworks/anaconda3/envs/nerf_factory/lib/python3.9/site-packages/pytorch_lightning/utilities/data.py", line 157, in _update_dataloader

Did you solved??

I have encountered the same problem before, until I installed Pytorch_ Righting=1.6.0, this issue has been resolved.
