Getting compile error: Invalid input token: 'name'

I was testing the data frame snippet from the example in the dataframe PR (#510). However, when running inside the repl (built from tip of master), I got the below error:

REPL: Compile error: Invalid input token: 'name':

You'll need to run this inside the Python REPL, not the Weld REPL; the Weld REPL is just to test compiling Weld language expressions :)

Oh, I see. Thanks for the help.

Hi @sppalkia. After a little bit of experimenting, I encountered an error. For context, I was trying to run the following commands on Mac under weld-python:

$ rustup default nightly
$ python setup.py develop

It was on the second command that I had a problem. (I just used python3 instead of python). The following error was reported:

Traceback (most recent call last):
  File "./setup.py", line 8, in <module>
    from setuptools_rust import RustExtension
ModuleNotFoundError: No module named 'setuptools_rust'

I did try to pip3 install the above module (which passed), and then try the command again. However, that failed, with the same error. Do you know what might be the cause of this error?
