Deserialize header failed: while making lstmf file

[Meet Yogi]

I'm using command

tesseract tiff_file_path name_of_lstm_file lstm.train

for example

tesseract batch3.tiff batch3 lstm.train

while doing so I'm getting the following error

Tesseract Open Source OCR Engine v4.1.1 with Leptonica

Failed to read training data from /home/petpooja/meet/ocr/tesseract_annotated_images/training_data_phase_1/cn_id_in_gstno_cleaned_images/batch3.lstmf!

How can it be solved?

I have checked the box file and verified annotations there is no issue with it

What is inside your training_text file? I had similar issue when the lines in that file were too long... try to make them as short as 5-7 words (and then break it with a newline)
