Pandas Missing required dependencies ['numpy']

Question

I am currently following a beginners introduction to machine learning. While entering in the command: import pandas as pd in the python shell in terminal, I get an error reading:

ImportError: Missing required dependencies ['numpy'].

I already looked at the other similar question, tried that solution, but still received the same error.

I did, and receive this: Requirement already satisfied: numpy in /usr/local/lib/python2.7/site-packages. Then why I try it again, I get the same error. — sdksmkfnajnf, May 27 '17 at 19:27
Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. If you're working with a numpy git repo, try `git clean -xdf` (removes all files not under version control). Otherwise reinstall numpy. — sdksmkfnajnf, May 27 '17 at 19:30
Keyword *Otherwise reinstall numpy*... So, uninstall, then reinstall — OneCricketeer, May 27 '17 at 19:32
I did, and still does not work. pip uninstall numpy and then pip install numpy — sdksmkfnajnf, May 27 '17 at 19:33

Looks like you might be running on a Mac and perhaps using the default system python. For whatever reason you don't have a complete installation. you have pandas but not numpy. I'm not sure which packages the tutorial you are following uses, but I would recommend installing the Anaconda python distribution as it includes pandas, all its dependencies and much more, including the scikit-learn package often used for machine learning.

If you want to know more about installing a Python environment for machine learning on a Mac, there is a good tutorial on machinelearningmastery.com.

This doesn't have anything to do with incompatibility. As @Peter mentioned, you simply don't have NumPy and should install through Anaconda. Here is the code within pandas that is giving you the error:

# Let users know if they're missing any of our hard dependencies
hard_dependencies = ("numpy", "pytz", "dateutil")
missing_dependencies = []

for dependency in hard_dependencies:
    try:
        __import__(dependency)
    except ImportError as e:
        missing_dependencies.append(dependency)

if missing_dependencies:
    raise ImportError("Missing required dependencies {0}".format(missing_dependencies))
del hard_dependencies, dependency, missing_dependencies

Notice there is nothing here about version.

Yup I wasn't using anaconda but now it works. Thank you! – sdksmkfnajnf May 27 '17 at 19:51 — sdksmkfnajnf, May 27 '17 at 19:51

I had a same problem. I don't know what is the cause of the problem, but it seems to deal with how numpy is installed. You can try the following:

Install pandas
Uninstall numpy
Download numpy whl for your needs from here
Install numpy from downloaded whl

That worked for me!

I get the same error message with my Anaconda installation when I forget to activate the environment:

Testcode: import_pandas.py:

import pandas
print('Pandas import succeeded!')

Run import_pandas.py with ImportError:

Microsoft Windows [Version 10.0.16299.1146]
(c) 2017 Microsoft Corporation. All rights reserved.

C:\Users\peter\demo>python import_pandas.py
Traceback (most recent call last):
  File "import_pandas.py", line 1, in <module>
    import pandas
  File "C:\Users\peter\AppData\Local\Anaconda3\lib\site-packages\pandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

However, after activating conda everything works perfectly fine:

C:\Users\peter\demo>activate
C:\Users\peter\demo>conda.bat activate

(base) C:\Users\peter\demo>python import_pandas.py
Pandas import succeeded!
