Error code:
import pandas as pd
indexer = pd.array(['one','two'])
arr = pd.array([1, 2, 3])
pd.api.indexers.check_array_indexer(arr, indexer)
check_array_indexer checks if indexer is a valid array indexer for array. Take 2 arguments: an array that is being indexed and an indexer that is used to index. The error comes when the indexer has a different data type than integer and boolean.
Fix code:
import pandas as pd
indexer = pd.array([0,2])
arr = pd.array([1, 2, 3])
pd.api.indexers.check_array_indexer(arr, indexer)
