Hi @ericOnline

I also faced the same issue and I eventually found that upgrading the databricks runtime version from my current "5.5 LTS (includes Apache Spark 2.4.3, Scala 2.11)" to "6.5(Scala 2.11,Spark 2.4.5) resolved this issue.

Though the official documentation says that dbutils.library.installPyPI is supported after runtime version 5.1 but that does not seem to be the case here.

Thanks
