Failed scheduling due to utils.py 'basestring' is not defined?

[trzytematyczna]

Hi,
I am trying to use your parser, and while running the command pipeline admin$ python pipeline.py BuildDataset --start 2000 --end 2001 --local-scheduler I am getting the error, which is connected to " NameError: name 'basestring' is not defined" in the utils.py. I looked at the code, but tbh I struggle to get what the variable basestring suppose to be. Any indications what can I check or how can I solve this much appreciated!

Error:

===== Luigi Execution Summary =====

Scheduled 2 tasks of which:
* 1 failed scheduling:
    - 1 BuildLCCAuthorRepdocCorpusTfidf(start=2000, end=2001)
* 1 were left pending, among these:
    * 1 had dependencies whose scheduling failed:
        - 1 BuildDataset(start=2000, end=2001)

Did not run any tasks
This progress looks :( because there were tasks whose scheduling failed

This is due to incompatibility with Python 3. The basestring type was a common base type for str and unicode that was removed in Python 3, when the default str type was changed to be unicode. The easiest fix for this is to run it with Python 2.

If you'd like, you can replace that line with if isinstance(self.base_paths, str):. There may be other incompatibilities with Python 3 after this though. If you're up to it, I'm glad to merge in a PR that gives full compatibility. You can try using the 2to3 tool to help.
