Basic Python Data Analysis Tutorial: NumPy Learning Guide (2nd Edition), chapter 1th NumPy QuickStart, this chapter first describes how to install NumPy and related software in different operating systems, and gives a simple example code that uses NumPy. We will then briefly introduce Ipython (an interactive shell tool). As stated in the preface, SciPy and NumPy have close ties, so you will see scipy many times. At the end of this chapter, we'll show you how to take advantage of online resources so that you can get help online when you're stuck with a problem or unsure about the best way to solve it. This section introduces hands-on practice: Installing NumPy, Matplotlib, scipy, and Ipython on Windows.
1.4 Hands-On practice: Install NumPy, matplotlib, scipy, and Ipython on Windows
Installing NumPy on Windows is required, but fortunately, the installation process is not complicated and we will elaborate on it below. It is recommended that you install Matplotlib, scipy, and Ipython, although this is not required for the use of this book. We will follow the steps below to install the software.
(1) Download the NumPy Windows Installer from the SourceForge website:
http://sourceforge.net/projects/numpy/files/
Please select the appropriate version. In, we have chosen Numpy-1.7.0-win32-superpack-python2.7.exe.
(2) When the download is complete, double-click Run Setup.
(3) Now, we can see a description of NumPy and its characteristics, as shown in. Click the Next button to continue the installation.
(4) If you have installed the Python,numpy installation program should be able to automatically detect. If Python is not detected, your path may be incorrectly set. At the end of this chapter, we have listed some online resources for readers who are having problems installing numpy.
(5) In, the Setup program successfully detects that Python 2.7 is installed on the system, click the Next button to continue the installation, otherwise click the Cancel button and install Python (NumPy cannot be installed separately from Python). Continue clicking on the Next button, you cannot go back to the previous step from this step, so please confirm that you have selected the appropriate installation path and other installation options. Now that the real installation process has started, you need to wait a while.
(6) SciPy and matplotlib can be installed through Enthough, the address is www.enthought.com/products/epd.php. During the installation process, you may need to place a file Msvcp71.dll under directory C:\Windows\system32. You can download this file from here: www.dll-files.com/dllindex/dll-files.shtml?msvcp71. The Ipython installer under Windows can be downloaded by visiting Ipython's official website: http://ipython.scipy.org/Wiki/IpythonOnWindows.
What did you just do?
We have installed NumPy, SciPy, Matplotlib, and Ipython on Windows.
