Failed to load any lstm-specific dictionaries for lang XXXX!! #79

Closed Jitendradubey closed 5 years ago

Jitendradubey commented 5 years ago

Hi,

We have used OCR-D for training the tesseract 4.0, We have trained tesseract 4.0 by using ocrd-train with error rate is 0.3, But We are going to test with latest generated trained model, We got error.

Error : Failed to load any lstm-specific dictionaries for lang XXX!!

Thank in advance.

Most likely a path problem. You either have to copy your model to a place where Tesseract looks for it or you have to tell Tesseract where to look for your new model. Pls. refer to the Tesseract manual.

@Jitendradubey, you did not get an error. You only got an informational message Failed to load any lstm-specific dictionaries for lang XXX!! from Tesseract. As you have created a new model, that is normal. Either ignore the message or add a dictionary to your model.

Could this be marked as a warning instead of an error perhaps @stweil? Seems to be a common issue of confusion for trained models not packaged with any dictionaries (such as those produced by ocrd-train). Even @cneud stumbled over it this morning :)

It is not marked as an error (no "error" in the message text, that's why I wrote "you did not get an error"). And yes, it is confusing, like other messages of Tesseract, too.

When thinking in logging categories, it might even be less than a warning, maybe log level INFO.

Adding log levels to the Tesseract code and replacing the different methods used for logging today is one of many open tasks. That would also allow better integration of libtesseract into other software (like for example tesserocr).
