Error performing OCR with Tesseract: read_params_file: Can't open deu

Question

While specifiing the language pack used to perform the OCR, i get the following error (for every language pack corresponding):

read_params_file: Can't open deu

I used the command as described in the wiki:

tesseract test.tif out -1 deu

The .traineddata files are located under tessdata and the TESSDATA_PREFIX is set to the parent directory of tessdata. The process works under default without given language information.

I have Tesseract 3.05 installed on Windows 10.

Answer 1

The command should be

tesseract test.tif out -l deu

with "l" instead of a "1".

Answer 2

This is a common response, if there is anything wrong with your parameter setup. Either if you add a param which is not defined - like "1" or if you add params in the wrong order.

E.g.

if you add the hocr parameter , you have to place it after the -l parameter. In the official docs there is no case in which hocr is used with the language parameter.

Wrong:

PS C:\Users\Mememe\Desktop\tesseract> & 'C:\Program Files (x86)\Tesseract-OCR\tesseract.exe' 'C:\Users\mememe\Desktop\tesseract\img.jpg' out hocr -l deu
read_params_file: Can't open l
read_params_file: Can't open deu
Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica

Better:

'C:\Program Files (x86)\Tesseract-OCR\tesseract.exe' 'C:\Users\Mememe\Desktop\tesseract\img.jpg' out -l deu hocr
Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica

So if you have this error check:

• Are all your parameters defined? (Check the help parameter to get a list of all available params)
• Are all parameters in the right order? (Good Luck figuring out :) )
• Are the paths I defined correct? Are there dots or spaces I should double check?

If this doesn't work - double check. Otherwise feel free to add your answer here.
