How to run unoconv via subprocess in django python?

Question

If I run unoconv -f pdf test_pdf.docx in terminal, it's working fine. But if I run it in subprocess, I got this error

subprocess.run(['unoconv', '-f', 'pdf', path],  shell=True)

unoconv: Cannot find a suitable pyuno library and python binary combination in 
/usr/lib/libreoffice
ERROR: No module named 'uno'

unoconv: Cannot find a suitable office installation on your system.
ERROR: Please locate your office installation and send your feedback to:
   http://github.com/dagwieers/unoconv/issues

Please help me resolve this problem
