Current Behavior:

When trying to finetune the training I am using
lstmeval --model ~/tesstutorial/engtrain/eng/eng.traineddata --eval_listfile ~/tesstutorial/engeval/eng.training_files.txt --traineddata ~/tesstutorial/engtrain/eng/eng.traineddata

I am getting an error

Loaded 72/72 lines (1-72) of document /home/prashant1/tesstutorial/engeval/eng.Impact_Condensed.exp0.lstmf
Deserialize failed

I tried referring issue #792 but couldn't find helpful.

please let me know what could be the fix.

Does the file exist?

[Prashantptnk]

Yes, the file eng.Impact_Condensed.exp0.lstmf exists.

[Shreeshrii]

What is the file size? How did you generate it? Did you copy it between different platforms?

[Prashantptnk]

the file is auto-generated. I have not copied it. The size is around 403.9 kb.

Please see https://github.com/Shreeshrii/tess4training/blob/master/4-impact_from_full.log for log from a successful run of tesstutorial from a few months ago. If you follow the instructions then there should be no errors.

Old issue, probably a user error.
