VIRTUALENV Installation

Pip Install Virtualenv

Well, now, if you need to do numerical research, you need to install

Python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

So a series of packages, and you want to install in a separate environment.

Create a new directory. (Anywhere)

mkdir D:\Python

And then

Virtualenv Numenv (Here's the name as you write)

Then you will find that a numenv folder was generated

And then

Scripts\activate activation

Create a new TXT file and write the package you need to install.

(only need to write NumPy scipy these names, python-can be removed)

Pip Install-r requirements.txt

Then it will be installed automatically.

Finally, if you want to use this new environment in Pycharm.

The path to the Python interpreter needs to be changed.

In the Settings-project: Python--python interpreter inside.

It is important to note that when installing scipy, it is very likely that it will fail

Also, say something about using PIP to install the local file method

Pip install numpy--find-links= path name
