TDML: Error occured while writing to garbage collector file

I was facing the error above in teradataml py package on Win11, when using Dataframe.from_query(). But I am sure the exception would be triggered in (many) other methods.

Why ? Because of a generic bug in garbagecollector.py constructor, namely the filename of the GarbageCollector contains one or multiple : chars, which is invalid in Windows.

Note this is teradataml v20.0.0.3 No issue if run in linux/WSL.

Solution

  • Had a closer look at it and the invalid name was due to a teradataml package function that gets the IP address of the TD server.

    It can't resolve localhost (am using SSH tunnel), resulting in :: in the filename which Windows doesn't accept.

    I switched to 127.0.0.1 in the connection string and problem solved.
