ValueError: assignment destination is read-only

[SuleBai]

Hi, thanks for your great work.

When I try to reproduce the results using command below

bash scripts/train_clipself_coco_image_patches_eva_vitl14.sh

I ran into the error ValueError: assignment destination is read-only, and refers to this line

CLIPSelf/src/training/data.py

Line 370 in 1c7fe9c

np_old_image[segm_map != ann['id']] = 114

Is there any bug in this code or what should I do to avoid this bug?

Thanks.

Hi! Please take care of the version of Pillow. I am using Pillow==9.1.0

Thanks for your quick reply and this has solved my problem.

And I have another question what should I do if I want to train the openai clip or the clip variants provided by the openclip using this script?

bash scripts/train_clipself_coco_image_patches_eva_vitl14.sh

I think I should modify the config --model, --pretrained, --embed-path, am I right?
And what should I do to produce the --embed-path npy file for the model I use?

Thanks again.

You can try this
np_old_image = np.asarray(old_image.copy()).copy()
