Hi,

The error message and stack trace doesn't seem to suggest that this is a failed pytest issue. If that's true, can you please try to replicate what's being invoked from `src\tests\test_calculate_psi_for_each_column.py` in a Python REPL?

And separately, have you confirmed that the pyspark installation was successful? Depending on how you installed pyspark, are you able to start pyspark by itself (independent of `findspark`) such as `$SPARK_HOME/bin/pyspark`?

Thanks.
