John Snow Labs Configurations

 

Installed Library Version Settings

Each version of the John Snow Labs library comes with a hardcoded set of versions for very of product of the John Snow Labs company.
It will not accept library secrets which correspond to versions do not match the settings. This essentially prevents you from installing outdated or new but not deeply tested libraries, or from shooting yourself in the foot you might say.

You can work around this protection mechanism, by configuring jsl.settings.enforce_versions=False. This will ignore bad secret versions.

from johnsnowlabs import *
jsl.settings.enforce_versions=False
jsl.install(secret='1.2.3-My.Custom.or.Outdated.Secret')
