-----------------------------------
Summary: Is there a good way to convert data types from numpy
types to pyarrow DataType?
Key: ARROW-8642
URL: https://issues.apache.org/jira/browse/ARROW-8642
Project: Apache Arrow
Issue Type: Wish
Reporter: Anish Biswas
Pretty much what the title says. Suppose I have a numpy array and its a
numpy.int8 type. How do I convert it to a pyarrow.Datatype intuitively? I
thought a Dictionary lookup table might work but perhaps there is some better
way?
Why do I need this? I am trying to make pyarrow arrays with from_buffers(). The
first parameter is essentially a pyarrow.Datatype. So that's why. I have
validity_bitmaps as a buffer of uint8 and that's why I am using from_buffers()
and not pyarrow.array().
