How to handle the case when my dataset contains images with no texts. .i.e empty annotations files
Right now it gives - ValueError: need at least one array to stack error

[Wovchena]

I assume that happens in

text-detection-fots.pytorch/datasets.py

Line 170 in 04b969c

return transform(img, np.stack(quads), texts, self.normalizer, self)

(that would be simpler if you left the full error with traceback)

In that case you should build your tuple with np.array() (or None) instead of np.stack(quads). But I can't say for sure that the rest of the code won't complain that you return an empty array.
