Pandas Missing required dependencies ['numpy']

Question

enter image description here

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.

• Sagar: install numpy first.
• sdksmkfnajnf: 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.
• Sagar: I think numpy version is not compatible with pandas.
• OneCricketeer: Can you import numpy? If so, then your pandas is broken
• sdksmkfnajnf: When I try to, I get this:

Answer 1

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.

• sdksmkfnajnf: Yup I wasn't using anaconda but now it works. Thank you!

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:

1. Install pandas
2. Uninstall numpy
3. Download numpy whl for your needs from here
4. Install numpy from downloaded whl

That worked for me!

Answer 4

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!
