python - AttributeError: module 'numpy' has no attribute '__version__'

Question

I updated my computer today, and am getting the following error message when I attempt to import pandas:

import pandas as pd        
AttributeError: module 'numpy' has no attribute '__version__'

I have tried the suggestions from the following links:

1. AttributeError: 'module' object has no attribute '__version__'
2. AttributeError: 'module' object has no attribute '__version__'

I do not have any files names numpy.py other than the numpy package.

I am running anaconda2 within windows 10, and have created a python 3.5 virtual environment.

Following is the full error message:

Python 3.5.5 | packaged by conda-forge | (default, Apr  6 2018, 16:03:44) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\j267156\AppData\Local\Continuum\anaconda2\envs\sf35\lib\site-packages\pandas\__init__.py", line 23, in <module>
    from pandas.compat.numpy import *
  File "C:\Users\j267156\AppData\Local\Continuum\anaconda2\envs\sf35\lib\site-packages\pandas\compat\numpy\__init__.py", line 10, in <module>
    _np_version = np.__version__
AttributeError: module 'numpy' has no attribute '__version__'

Edit: performing the following commands gives an error

import numpy
print(numpy.__file__)
AttributeError: module 'numpy' has no attribute '__file__'
print(numpy.version.version)
AttributeError: module 'numpy' has no attribute 'version'

Edit2: perfoming the following commands gives me the following errors:

import numpy as np
np.zeros(5)
#AttributeError: module 'numpy' has no attribute 'zeros'
vars(np).keys()
#dict_keys(['__name__', '__package__', '__spec__', '__loader__', '__doc__', '__path__'])

Edit3: the following commands result in the following output:

import numpy as np    
In [7]: np.__path__
    Out[7]: _NamespacePath(['C:\\Users\\j267156\\AppData\\Local\\Continuum\\anaconda2\\envs\\sf35\\lib\\site-packages\\numpy'])

    In [8]: np.__loader__
    Out[8]: <_frozen_importlib_external._NamespaceLoader at 0x2033a3c8080>

Answer 1

Try this

In Jupyter notebook first uninstall the existing numpy by using !pip uninstall numpy.

Then install it !pip install numpy. Now restart the kernel(Python Notebook). It will work.

Answer 2

You may have named your program/script 'numpy'. I also had that then i renamed my program and then it works. It happens because when you name your program similar to a module the import attribute clashes between programs and modules

Answer 3

Just had this issue after conda chose to update numpy from 1.13.3 to 1.14.3. Reverting numpy via procedure in http://blog.rtwilson.com/conda-revisions-letting-you-rollback-to-a-previous-version-of-your-environment/ sufficed to recover functionality, followed by pinning the version in the environment.

Answer 4

Have you tried this:

pip uninstall -y numpy
pip uninstall -y setuptools
pip install setuptools
pip install numpy

Answer 5

I had this error today while I was running a "brew upgrade" on MacOS and upgrade failed on matplotlib.

<TLDR/>

I run pip (v 2.x) and pip3 installed. It turned out I had not installed numpy with pip3. I ran

pip3 install numpy

brew upgrade then ran successfully.
