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?
