Opencv Error!

[zobeirraisi]

I get the following error during training of synth and IC15 , after updating the new data_loader.py ., It was working before the new update.
I try to install different version of OpenCV , it didn't solve.

cv2.error: OpenCV(3.4.2) /io/opencv/modules/imgproc/src/color.hpp:253: error: (-215:Assertion failed) VScn::contains(scn) && VDcn::contains(dcn) && VDepth::contains(depth) in function 'CvtHelper

@zobeirraisi Sorry! I have released the code for IC15 just now.

Thanks for your quick reply, 👍
Now I got this error:

for index, (real_images, real_gh_label, real_gah_label, real_mask) in enumerate(real_data_loader):
ValueError: too many values to unpack (expected 4)

@zobeirraisi Because it returns the confidence, you can change it as below:
for index, (real_images, real_gh_label, real_gah_label, real_mask) in enumerate(real_data_loader):
syn_images, syn_gh_label, syn_gah_label, syn_mask, __ = next(batch_syn)

I am still receiving the above “openCV error “ message in data_loader.

@zobeirraisi Could you show me your whole error information

[zobeirraisi]

This is the whole error for both trainic15 and trainSyndata: ==== syn_images, syn_gh_label, syn_gah_label, syn_mask,__ = next(batch_syn) File "/home/karim/.local/lib/python3.6/site-packages/torch/utils/data/dataloader.py", line 346, in __next__ data = self.dataset_fetcher.fetch(index) # may raise StopIteration File "/home/karim/.local/lib/python3.6/site-packages/torch/utils/data/_utils/fetch.py", line 44, in fetch data = [self.dataset[idx] for idx in possibly_batched_index] File "/home/karim/.local/lib/python3.6/site-packages/torch/utils/data/_utils/fetch.py", line 44, in <listcomp> data = [self.dataset[idx] for idx in possibly_batched_index] File "/home/karim/Desktop/Text/Detection/CRAFT/CRAFT-Reimplementation/data_loader.py", line 374, in __getitem__ return self.pull_item(index) File "/home/karim/Desktop/Text/Detection/CRAFT/CRAFT-Reimplementation/data_loader.py", line 319, in pull_item image, character_bboxes, words, confidence_mask, confidences = self.load_image_gt_and_confidencemask(index) File "/home/karim/Desktop/Text/Detection/CRAFT/CRAFT-Reimplementation/data_loader.py", line 390, in load_image_gt_and_confidencemask image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB) cv2.error: OpenCV(4.1.1) /io/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cvtColor' =======

@zobeirraisi I think maybe is your image path error,please check your data path.

[zobeirraisi]

It solved thanks, Yes, my synthText path was wrong!

I meet the same error,but my synthtext path is right,do you have some advice?thanks.

I meet the same error,but my synthtext path is right,do you have some advice?thanks.

I also meet the same error. I found some images that are suffixed with .gif. You can delete the images. I hope the advice is useful to you.
