Calling
to_snowpark_pandason a Snowpark Python DataFrame without first performingimport snowflake.snowpark.modin.plugincurrently raises an error (see attached JIRA for exact reproduction). This was not the case in previous releases, and this PR fixes internal imports such that performing this operation implicitly initializes Snowpark pandas.After this PR, when
to_snowpark_pandasis called without explicitly initializing Snowpark pandas, one of two things happens:This is the same error as if the user had tried to
import snowflake.snowpark.modin.pluginwithout installing the modin dependency.import snowflake.snowpark.modin.plugin. If the user performsimport modin.pandas as pdafterwards, the modin namespace will be set up with Snowpark pandas behavior.
