I have trouble using pip. For example:
pip install numpy --upgrade
Gives me the following error:

Here are some clues:
(i) I have the same error when I try to run Spyder. It also appears when I try to to install other packages wtih pip, pandas for example.
(ii) I have the feeling, that this is related to the default encoding since sys.getdefaultencoding gives me 'ascii'
Note that it works well if I do it in a virtualenv.
I'm new to ubuntu so I might have done someting wrong.
Setup: python 2.7.6; pip 7.1.2; ubuntu 14.04.03.
Thank you for your help.
I had the same issue. In my case, it comes from a non-standard character in a module description.
I added a
print f.path
in the script
/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py
before line 2025, which allowed me to identify the file which was raising an error. It appeared to be the file
/usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info
whose author has a name containing the ö character, which can not be read. I simply replaced the "Göran" with "Goran" in this file and it fixed the problem.
hope this helps.

I am using anaconda Powershell Prompt in Win10. UnicodeDecodeError was reported when installing package with pip (version: 21.2.4). I found this error would reported with the kernel Python 3.6.7 and Python 3.9.7.Both the installation and the upgrade failed and reported the same error. I've tried the following command.
pip install simplejson
pip install simplejson --upgrade
The package can be anything and report the same bug.
Same error was reported using the Windows CMD. I tried the following command using Windows CMD.
py -m pip install simplejson
py -m pip install --upgrade pip
Here is the error report I got.

UnicodeDecodeError: 'gbk' codec can't decode byte 0xff in position 0: illegal multibyte sequence
I have reinstalled the pip, Anaconda, and the python interpreter. It still failed. I think it has nothing to do with the pip. Something went wrong with the input stream. The default decode format is "GBK". I tried to change decode format to "utf-8" with the following command. It failed again with the same error.
chcp 65001
Thanks the suggestion from #Mobfi, I tried other similar commands, which return the same error notification.
chcp 437
chcp 850
Thanks the suggestion from #BoarGules, I start python with utf-8 decoder and tried to install/upgrade package with pip.
py -X utf8
I started the python console in powershell.
import pip
pip.main(['install', 'simplejson'])
Besides the similar traceback, I got another new traceback:
*same as aforementioned traceback*
File "E:\Program Files\Anaconda3\lib\codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
Anybody can help? Any potential solution, clues or similar experiences is welcomed.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 9: ordinal not in range(128)
After startlingly generous help from Padraic, we eventually figured out that the problem was my computer name, which was Fredrik-Bärbar (notice the ä, i.e. 0xe4 in code page 850, there in the 10th place, or 9th place using Python's 0-based indexing).
(This error is related to that in Pip Error when installing, another question solved by Padraic.)
While running python make_dataset in the quick start example for Pylearn2, I've run across an import error in a Theano .so file. The heart of the issue seems to be this: undefined symbol: _gfortran_st_write. I'm running development versions of numpy, scipy, Theano, and Pylearn2. Any ideas?

The problem was resolved after removing ATLAS, installing OpenBLAS, reinstalling numpy + scipy + theano, and then installing Pylearn2 from source.
See https://github.com/Theano/Theano/blob/master/doc/install_ubuntu.txt#L70 of the Theano install guide for a more detailed explanation.
