title: how to use tessdata_best for tesseract (pytesseract). What are the arguments and procedure?
body: <p><strong>TL;DR: How do I install <code>tessdata_best</code> to use with<code>pytesseract</code> inside <code>conda</code> in <code>Ubuntu 18</code></strong>?</p>
  <p>I have been using <code>pytesseract</code> inside <code>conda</code> environment for quite some but there is a need to improve the accuracy and I found out that <code>tessdata_best</code> gives you the best accuracy. How can I install and use that version? I am using <code>Ubuntu 18</code> and have to work with <code>pytesseract</code>.</p>
  <p>I have my <code>tesseract</code> installed at <code>/usr/share/tesseract-ocr/</code> and inside it there is only 1 <code>tessdata</code>.</p>
  <p><strong>Do I need to get the <code>tessdata_best</code> from github by copying it to the directory <code>/usr/share/tesseract-ocr/</code> alongside <code>tessdata</code>?</strong></p>
  <p>Even then, if I want to use <code>tessdata-best</code>, what do I have to use? Do I need to change the <code>config</code> as  <code>--oem 0/1/2/3</code>?</p>
  <p>Third and last thing is that I have my <code>language.trainedata</code> files at <code>/home/deshwal/anaconda3/envs/py36/share/tessdata/eng.traineddata</code>. Do I need to paste the <code>tessdata_best</code> at this location too? Becuse when I try to change the language dir, it gives me error as as:</p>
  <p><code>/home/deshwal/anaconda3/envs/py36/share/tessdata/equ.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your &quot;tessdata&quot; directory. Failed loading language \'equ\' Tesseract couldn\'t load any languages! Could not initialize tesseract.'</code></p>
