pip install nupic throws error #3897

Open arb-git opened 3 years ago

Hi!

I was trying to get acquainted with nupic library, but it does not work from the very beginning, the "pip install nupic" command.

Running this in a Google Colab notebook (and locally), I get the following error log: Using cached https://files.pythonhosted.org/packages/86/e8/f31a7c9a3b471f6125abc8addd37c17760e00affb45d6db088394a360086/unittest2-0.5.1.tar.gz Added unittest2==0.5.1 from https://files.pythonhosted.org/packages/86/e8/f31a7c9a3b471f6125abc8addd37c17760e00affb45d6db088394a360086/unittest2-0.5.1.tar.gz#sha256=aa5de8cdf654d843379c97bd1ee240e86356d3355a97b147a6f3f4d149247a71 (from nupic) to build tracker '/tmp/pip-req-tracker-f2clgsrs' Running setup.py (path:/tmp/pip-install-1j0aqyyp/unittest2/setup.py) egg_info for package unittest2 Running command python setup.py egg_info Traceback (most recent call last): File "", line 1, in File "/tmp/pip-install-1j0aqyyp/unittest2/setup.py", line 12, in from unittest2 import version as VERSION File "/tmp/pip-install-1j0aqyyp/unittest2/unittest2/init.py", line 40, in from unittest2.collector import collector File "/tmp/pip-install-1j0aqyyp/unittest2/unittest2/collector.py", line 3, in from unittest2.loader import defaultTestLoader File "/tmp/pip-install-1j0aqyyp/unittest2/unittest2/loader.py", line 92 except Exception, e: ^ SyntaxError: invalid syntax Cleaning up...

Is there anything that can be done about it? Honestly, if I can't even install it, what use is it to me. But maybe I am missing something simple. Any help would be much appreciated!

Regards, A.

Notice the error message.

File "/tmp/pip-install-1j0aqyyp/unittest2/unittest2/loader.py", line 92
except Exception, e:
^
SyntaxError: invalid syntax

It's pointing out a syntax error on the line that contains except Exception, e:.

Python3 exceptions are of the format except Exception as e:. https://docs.python.org/3/reference/compound_stmts.html#except

Python2 exceptions allow a comma or an "as". https://docs.python.org/2.7/reference/compound_stmts.html#except

You're trying to install it with Python3.7. The repo lists 2.7 as a dependency. https://github.com/numenta/nupic
