How to use old version traineddata in tesseract 4.0?

[HongEn Tsai]

hi sir.

I tried the current version (4.0) do some test and work fine but slow. I also tried some old version (about 3.x, just from the apt get ) and it workes good and fast.

now I'd like to use the old version traineddata in 4.0 environment so I download the traineddata file from the git and renamed it as "eng2"

then I used the following command:

tesseract ~/image.jpg output --oem 0 -l eng2

Now it only returns 

read_params_file: parameter not found: enable_new_segsearch

What should I do to use old version traineddata?
