Good morning!
Until yesterday I was using python 2.7 and using the following code for writing output files for my scripts:
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
But now I'm upgrading my code to python 3.7, so now I need to use importlib.reloadinstead of just reload. However, typing sudo -H pip3 install importlib on my shell gives me the following error:
Collecting importlib

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-install-3cz_3d6n/importlib/
After looking for solutions I also tried to upgrade setuptools, but that didn't fix my problem.
Many thanks in advance!
importlib at PyPI is an outdated package intended for very old Python versions. For new versions of Python importlib is a module from the standard library, you don't need to install it, it's always available.

I am trying to run this example on MacOS High Sierra. It requires installing the page package, which requires installing the pytodos package, which requires installing the enum package, installation of which fails.

Note that I've tried to do the same on Ubuntu. And I had to repeat every step. However, installation of enum failed with this error instead:

What am I doing wrong?
You went wrong at pip install page.
You were supposed to provide your own module page.py, as described here.
pip install page pulled in some garbage and unrelated/unmaintained projects from PyPI.
I'm new to Python (coming from C++), running some test code in Brackets. Now pylint complains saying:
C0111 > Missing module docstring [missing-docstring # 1,0]
so I tried installing it:
Manuelas-MacBook:~ manu$ sudo -H pip install docstring
Collecting docstring
Downloading docstring-0.1.2.4.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

import docstring
File "/private/tmp/pip-build-ex4m9h3o/docstring/docstring/__init__.py", line 11, in <module>
from utils import Endpoint
ModuleNotFoundError: No module named 'utils'
So I installed utils:
sudo -H pip install utils
Now I am stuck with this:
Manuelas-MacBook:~ manu$ sudo -H pip install docstring
Collecting docstring

from utils import Endpoint
ImportError: cannot import name 'Endpoint'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-5bn12ekx/docstring/
And I don't really know how to go from here.
I had recently installed python3 (on Mac). Could I have a version collision?
Manuelas-MacBook:~ manu$ python --version
Python 3.6.0 :: Anaconda 4.3.1 (x86_64)
Manuelas-MacBook:~ manu$ pip --version
pip 9.0.1 from /Users/manu/anaconda/lib/python3.6/site-packages (python 3.6)
The error message is quite unclear. Acutally, pylint doesn't need any extra module : it just wants you to document your module.
You may want to take a look at this question to disable this warning.
The other answer seem to be probably helpful as I am getting exactly the same problem on my box (Linux Mint, Python 3.6). The reason may be that docstring is not (yet) compatible with Python3 .

I wanted to do LDA on some data and so followed this example:
http://scikit-learn.org/stable/auto_examples/decomposition/plot_pca_vs_lda.html#example-decomposition-plot-pca-vs-lda-py
however, on trying:
from sklearn.discriminant_analysis import LinearDiscriminantAnalysis
I got an import error. Huh, maybe this is a new function, I thought. So I updated scikit-learn via conda from 0.15.2 to 0.17. But now I can't even import sklearn:
import sklearn
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):

from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \
ImportError: numpy.core.multiarray failed to import
I tried updating numpy and scipy using both pip and conda to no avail. I then tried a complete clean re-install of anaconda by:
rm -rf ~/anaconda
and a subsequent download of the .pkg from http://docs.continuum.io/anaconda/install#anaconda-install
Still I get the same error. Here are my OS and package details:
Mac OSX 10.5.2
bash-3.2$ conda -V
conda 3.18.6
scipy==0.16.0
numpy==1.9.1
scikit-learn==0.17
The last of these via pip freeze since I can't import it. I'm going nuts here. Any help much appreciated.
Try:
conda install numpy=1.10.1
I've had that module compiled against API version a but this version of numpy is 9 error before, and this solved it for me.
Installed Twilio successfully however when I attempt to import it in either the shell or terminal I get this error output:
Traceback (most recent call last):

File "/Library/Python/2.7/site-packages/twilio/rest/resources/util.py", line 5, in <module>
import pytz
ImportError: No module named pytz
Can anyone explain what is happening here? My version of Python is 2.7.9 and my pip installer is current as well. Output Error above is from importing in IDLE shell.
Twilio developer evangelist here.
The Twilio library requires pytz to be installed. Easiest way to get it installed is by running this on your terminal:
pip install pytz
Hope this helps
I've recently installed pylint on a windows 7 and when I run it I get the error:

I've followed the install instructions as best I can but can't seem to get past this.
Use this link to install pip properly How do I install pip on Windows?
then do the pip install pylint
then do go through this note http://docs.pylint.org/installation.html#note-for-windows-users
