pyspark - Why can't Pandas's isin() work with numpy.int64?

When trying to run the following code:

val1_index = df_playlists['pid'].isin(val1_playlist[0])

I received this error:

AttributeError: 'numpy.int64' object has no attribute '_get_object_id'

df_playlists is a Spark dataframe with the following column types:

[('pid', 'bigint'), ('tid', 'bigint'), ('pos', 'bigint')]

and val1_playlist is a 2d-array of type numpy.int64 . I tried replacing val1_playlist with a simple Python list like [0, 1, 2] and it works just fine. So does this mean I have to cast each element in val1_playlist into int and then call isin() or should I do something else?
