ValueError: Could not find a format to read the specified file in single-image mode

[SomayeKarimpour]

Hello when I ran the Training I got this error; ValueError: Could not find a format to read the specified file in single-image mode the full error message is :

`ERROR:root:Error processing image {'id': 0, 'source': 'shapes', 'path': '../newdata/valid/jpg\\C10000_0001_Band_10.jpg', 'mask_path': '../newdata/valid/jpg_mask\\C10000_0001_Band_10.jpg', 'width': 224, 'height': 224}
