Pip Install NumPy
Using the PIP command in a DOS environmentThe platform does not support, Python version is too high, numpy mismatch, just started the latest version of 3.7, download the 3.6 version, the installation was successful.
When Python installs its own selection path
Both Easy_install and Pip are used to download the management tools for installing the related resource bundles for the pypi of a common repository of Python, while the PIP is a easy_install version that provides better hints and removes package features. The Python official web-compiled MSI file already contains both tools, installed in the

Today, when installing NumPy, Python Version 2.7 required which is not found in the registry error, the solution is as follows.Some Python third-party libraries look for Python only under the hkey_local_machine\software\wow6432node\python\pythoncore\2.7 \installpath path of the registry. But the loaded 64-bit Python builds Python information under the HKEY_LOCAL_MACHINE\Software \python\pythoncore\2.7\installpath path. So, in cmd, enter regedit and th

The presence of NumPy makes Python a powerful matrix computing power, no less than MATLAB.Official documents (https://docs.scipy.org/doc/numpy-dev/user/quickstart.html)

PrefaceIn the implementation of the relevant clustering algorithm, in Python language implementation, will often appear in the array and matrix confusion, here to do a summary.Array arraysThe most basic (default) type of NumPy is an array, and his related operations are used to manipulate the elements as a numerical calculation (with the action of the element (with +,-,,/,* , etc.). Multiplication Examples: from
Brief introduction:The SCIPY package contains various toolkits dedicated to common problems in scientific computing. Its different sub-modules correspond to different applications. Like interpolation, integration, optimization, image processing, special functions and so on.SciPy can be compared with other standard scientific computing libraries, such as the GSL (GNU C or C + + Scientific Computing Library), or the MATLAB toolbox. SCIPY is the core package of the scientific computing program in P

Python Numpy array initialization and basic operations, pythonnumpy
Python is an advanced, dynamic, and multi-generic programming language. Python code often looks like pseudo code, so you can use a few lines of highly readable code to implement a very powerful idea.
I. Basics:
The main data type of Numpy is ndarray, which is a multi-dimensional array. It has the following attributes:
Ndarray. ndim: dimensi

Ndim (meaning of the spatial dimension) is the number of matrix columns print a.ndimprint b.ndim#.

1. What is NumPy
Very simply, NumPy is a scientific computing library of Python that provides the function of matrix operations, which are commonly used with scipy and matplotlib. In fact, the list already provides a representation similar to a matrix, but NumPy provides us with more functions. If contacted Matlab, Scilab, then
These two days have taken a lot of effort to carry a deep learning Python architecture, but Theano has limitations on Python and nunpy versions, so you can only use newer versions of Python and nunpy to make sure it's not obsolete. But the most recent version of Python and the latest edition of NumPy is a bit imperfect, a lot of installation steps to be completed in the command line, so it took me a lot of time, in order to sacrifice my installation
