[jira] [Commented] (ARROW-11939) Bug in `pa.PythonFile`?
[ https://issues.apache.org/jira/browse/ARROW-11939?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17303345#comment-17303345 ]
Diana Clarke commented on ARROW-11939:
--------------------------------------
{{PythonFile}} is expecting a file object, not a path to a file.
https://arrow.apache.org/docs/python/generated/pyarrow.PythonFile.html
For example:
{code}
import pyarrow
with open("foo.parquet", "rb") as f:
pyarrow.PythonFile(f)
{code}
