Import numpy throws error: SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \uXXXX escape

Question

I have installed pyzo and miniconda under Windows 10 and installed numpy and matplotlib using conda install.

Answer 1

So, for people having trouble in

import numpy

using Windows 10 + Anaconda:

I replaced all single '\' to double '\\' in

\Lib\site-packages\numpy\__config__.py

I could import numpy after that.

Answer 2

When conda installs packages, it replaces the prefix, to make things relocatable. Unfortunately, it does not intelligently escape backslashes, so on Windows, these unescaped backslashes lead to the error you see.

In recent versions of conda, we use forward slashes in prefix replacement, and this issue goes away. If you can update conda, go do that. If not, numpy has prefixes in the following files:

"Lib/site-packages/numpy/distutils/site.cfg"
"Scripts/f2py.py"
"Lib/site-packages/numpy/config.py"
"Lib/site-packages/numpy/distutils/config.py"

check the latter 3 especially, and replace any non-escaped backslashes ( \ ) with either escaped ones ( \\ ) or forward slashes

Answer 3

This is how it worked for me: double \ before and after users word.

For example: \\users\\admin\anaconda3\sample.wav

I am using python 3.6 on Windows 7

Not sure why the post keeps only one \ after and before users word in the path
