Preprocess Error

[Neal2020GitHub]

Hi, I encountered such error when I ran preprocess.py. Any idea how to solve it? Thank you!

(langsplat) ➜  LangSplat git:(main) ✗ python preprocess.py --dataset_path ./data/snacks 
[ INFO ] Encountered quite large input images (>1080P), rescaling to 1080P.
 If this is not desired, please explicitly specify '--resolution/-r' as 1
Traceback (most recent call last):  
  File "preprocess.py", line 126, in create

    seg_images, seg_map = sam_encoder(aug_imgs)
  File "preprocess.py", line 299, in sam_encoder
    masks_default, masks_s, masks_m, masks_l = mask_generator.generate(image)
ValueError: too many values to unpack (expected 4)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "preprocess.py", line 404, in <module>

In line 299, it seems that mask_generator.generate(image) returns a list of masks.

I also have the same problem

I have solved the problem, this is due to the reason that you have installed segment-anything before in your environment, you need to uninstall the segment-anything, and follow the README to install the segment-anything-langsplat author has provided. Then you can successfully run the code
