can only concatenate str (not "list") to str

[ShlomiRex]

I'm trying to run the example for laion-400m dataset (https://github.com/rom1504/img2dataset/blob/main/dataset_examples/laion400m.md):

img2dataset --url_list laion400m-meta --input_format "parquet"\
         --url_col "URL" --caption_col "TEXT" --output_format webdataset\
           --output_folder laion400m-data --processes_count 16 --thread_count 128 --image_size 256\
             --save_additional_columns '["NSFW","similarity","LICENSE"]' --enable_wandb True

But I get the following error:

C:\Users\Shlomi\AppData\Local\Programs\Python\Python312\Lib\site-packages\albumentations\__init__.py:24: UserWarning: A new version of Albumentations is available: 2.0.5 (you have 1.4.24). Upgrade using: pip install -U albumentations. To disable automatic update checks, set the environment variable NO_ALBUMENTATIONS_UPDATE to 1.

TypeError: can only concatenate str (not "list") to str

And then the program stops.
