Hi,

In tesserct-ocr config method i did used OEM & PSM for extract the text from image. But during process i got an exception like below mentioned

Error : "Error, unknown command line argument '-psm'"

Method tried:

using threw config variable

config_var = '--oem 3 --psm 6',
out = pytesseract.image_to_string(image,lang='eng',config=config_var)

using directly to the line

out = pytesseract.image_to_string(image,lang='eng',config= '--oem 3 --psm 6')

And also tried by replacing --psm into -psm .But it is not resolved.

The OEM is working in --oem 3 & --oem 1, but using 0,2 i get result as,

Failed loading language 'eng' , Tesseract couldn't load any languages! .

Do you use model with legacy engine support?

Do you understand what it mean when you use --oem 0?

So lets summarize it:

You asked tesseract to use legacy engine with some language model. tesseract failed.

Conclusion => you did not provided provided language model with legacy model.
