[Python] When I Try To Train a Tesseract Model I get a Compute CTC targets failed error

I am currently using tesseract 5.0 and am training a model. I have generated the png, box and the ground truth files for a thousand images. However, when I run the command:

make training MODEL_NAME=graphDetector START_MODEL=eng TESSDATA=../tessdata/ MAX_ITERATIONS=500 LEARNING_RATE=0.0001 PSM=11

I get the error:

Compute CTC targets failed for data/graphDetector-ground-truth/graph613.lstmf!

for every one of them.

Each image is a graph like this:

img

The ground truth files (.gt.txt) are like this:

1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 2,000 3,000 4,000 5,000 6,000 7,000

The box files are like this:
