title: Python3 : module 'tabula' has no attribute 'read_pdf'
body: <p>A <code>.py</code> program works but the exact same code, when exposed as API, doesn't work.</p>
  
  <p>The code reads the pdf with Tabula and provides the table content as a output. </p>
  
  <p>I've tried :</p>
  
  <pre><code>import tabula
  df = tabula.read_pdf("my_pdf")
  print(df)
  </code></pre>
  
  <p>and</p>
  
  <pre><code>from tabula import wrapper
  df = wrapper.read_pdf("my_pdf")
  print(df)
  </code></pre>
  
  <p>I've installed tabula-py (not tabula) on AWS EC2 running Ubuntu. </p>
  
  <p>More than read_pdf, I actually want to convert to CSV and give the output. But that doesn't work as well. I get the same no-attribute error i.e. <code>module 'tabula' has no attribute 'convert_into</code>.</p>
  
  <p>The .py file and the API file (.py as well) are in the same directory and are accessed with the same user.</p>
  
  <p>Any help will be highly appreciated. </p>
  
  <p>EDIT : I tried to run the same python file from the API as OS command (<code>os.system("python3 /home/ubuntu/flaskapp/tabler.py")</code>). But it didn't work as well. </p>
