I noticed the first time I ran a Python 3 program using the matplotlib, I received a warning that it was building a font cache and might take a minute.

After you have Python 3.5.1 installed, open a new Command Prompt Window.

Command Prompt in the search box that pops up when you click the Start Button.

Now youre ready to import the Matplotlib and NumPy packages in IDLE.

Notice when you install Matplotlib, the numerical package NumPy is installed at the same time.

Most likely you are trying to import a failed build of numpy.

When I am trying to import just datetime in IDE it works, unlike numpy (i just tried again, and it gave error no module named numpy ).

I have no idea how this happened - the only thing I did was trying to downgrade to python 3.6 and then going back for 3.7 again.

But thank for helping anyway.

Numpy How To Install NumPy

In this article we will learn how to install NumPy in Python.

Numpy Mac Operating System

Following pointers will be covered in this article, What is NumPy How to install NumPy On Mac Operating System Installing NumPy On Windows Operating System NumPy Installation On Ubuntu Operating System How to Install NumPy On Fedora Operating System Lets begin What is NumPy Python is open source object oriented interpreted language.

Of the many features, one of the important features that makes python a strong programming language is Python packages.

A lot of external packages are written in python which you can be installed and used depending upon your requirement.

Each script is a module which can be a function, methods or new python type created for particular functionality.

In this blog we will explain the process of downloading and installing numpy packages and how to use them in python environment on mac, windows, ubuntu and fedora operating systems.

The basics of python programming language are not covered in this blog.

For beginners, the basics of python programming language are covered in this Edureka blog.

All python packages are installed using pip Package Installer for Python.

You can view the details of all python packages and download them from Python Package Index (PyPI).

However, pip is automatically installed when you download and install python from python.org or any other python integrated environment.

Please read the blog for the best python integrated platforms which also provides loads of other functionalities.

Moving on with this Install NumPy in Python article NumPy Installation On Mac Operating System Now lets see how we can install numpy on a mac operating system.

This section details on both python 2.7 and latest version of python 3.7.

PYTHON 2.7 Open a terminal in your MacBook and type python to get into python prompt.

Press command () Space Bar to open Spotlight search.

Type in Terminal and press enter.

In the terminal, use the pip command to install numpy package.

Once the package is installed successfully, type python to get into python prompt.

After opening the terminal as detailed in step 1 above, use pip3 command to install numpy.

Moving on with this Install NumPy in Python article we will see how to install NumPy on Windows Operating System NumPy Installation On Windows Operating System Python is not installed by default in windows operating system.

You can download the required version of python from python.org.

Once python is installed successfully, open command prompt and use pip to install numpy.

However, pip is not installed.

If you want the complete package, download python from python.org and install it on your ubuntu operating system using apt install command.

Alternatively, you can install pip on ubuntu and then install numpy which is the easier of the two ways.

You will need root privileges on the system to install pip and numpy.

Open a terminal in ubuntu and install pip and pip3 using apt.

Once pip is setup you can use the same commands Moving on with this Install NumPy in Python article How to Install NumPy On Fedora Operating System Similar to Ubuntu operating system python is installed by default in fedora.

Use pip command to install Notice the difference in pip command for python3 specifically in fedora operating systems.

Secondly, be aware that installing numpy with pip, installed it for both Python2 and Python3 automatically.
