I am trying to use the tika package to Parse files. Tika is successfully installed, tika-server-1.18.jar runned with Code in cmd Java -jar tika-server-1.18.jar

My code in the Jupyter is:

Import tika 
from tika Import parser
parsed = parser.from_file('')

However, I receive below error:

According to Apache Tika's site, all new versions of the tika-server.jar will require Java 8.

24 April 2018: Apache Tika Release Apache Tika 1.18 has been released! This release includes bug fixes (e.g. extraction from grouped shapes in PPT), security fixes and upgrades to dependencies. PLEASE NOTE: The next versions will require Java 8. Please see the CHANGES.txt file for the full list of changes in the release and have a look at the download page for more information on how to obtain Apache Tika 1.18.

Current outdated docs for tika Python library claim that Java 7 is needed, but now Java 8 must be installed. This is because the current version of tika-server.jar is automatically downloaded at runtime if not found in your temp file.

After installing Java 8, my basic test code launched the server and worked without error.
