Failed in nopython mode with 32 bit Python

When I run the first example in Readme, I get this error:

although I have python 3.7.4 and am using 64 bit hardware.

@annagracecalhoun Thanks for posting this. Can you do

import sys
print(sys.version)

And paste the output here?

I see a line in the error that says

The 'parallel' target is not currently supported on Windows operating systems when using Python 2.7, or on 32 bit hardware.

This is actually a Numba error and not a Stumpy error so it leads me to believe that, indeed, the environment is wrong but it's hard to tell from here. Let's try to debug this together.

All of our code is unit tested on Windows, Linux, and Mac OSX with Python 3.6 and 3.7. I just checked our tests for Windows + Python 3.7.4 and there wasn't anything that jumped out at me (all of the tests passed). Of course, stranger things have happened and so your feedback is welcome.

Ah - there's me problem. The response was:
3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 21:26:53) [MSC v.1916 32 bit (Intel)]

I had seen in my computer settings that I have a 64 bit OS and assumed that also meant I had 64 bit "hardware" which must not be the case. Thank you for the help!

@annagracecalhoun Assuming that you are using a computer that was built/purchased in the last 5 years then I would be willing to bet that you are using 64 bit hardware (it's very rare to find 32 bit hardware these days). If I were to venture a guess, you may have simply installed the 32 bit version of Python .

If you are trying to familiarize yourself with the STUMPY API then you might consider playing with the Binder notebooks:

https://mybinder.org/v2/gh/TDAmeritrade/stumpy/master?filepath=notebooks

They have all of the software installed for you to tinker with.

@annagracecalhoun I'm gonna close this for now but feel free to reopen if you continue to have problems
