python3.6 的安装和numpy、opencv、pyrealsense2的安装

为了能够使用D435i相机的使用，进行准备工作，python3.6 的安装和numpy、opencv、pyrealsense2的安装。

创建一个虚拟环境：为了方便管理，自己python的虚拟环境都在D:\Anaconda3\envs中

WIn+R 打开命令行，输入cmd

转到要创建虚拟环境的位置，

输入：conda create -n python3.6 python=3.6 创建名为python3.6的虚拟环境

激活虚拟环境：activate python3.6

1.安装Numpy: pip install numpy

2.安装opencv: pip install opencv-python

如果报错信息为：

(python3.6) D:\Anaconda3\envs>pip install opencv-python
Collecting opencv-python

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "", line 1, in 
      File "C:\Users\2020s\AppData\Local\Temp\pip-build-4yawlglc\opencv-python\setup.py", line 10, in 
        import skbuild
    ModuleNotFoundError: No module named 'skbuild'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\2020s\AppData\Local\Temp\pip-build-4yawlglc\opencv-python\
You are using pip version 9.0.1, however version 22.0.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

    import skbuild
    ModuleNotFoundError: No module named 'skbuild'

这个报错不用管，直接用在命令行输入：    python -m pip install --upgrade pip

之后在安装opencv,就可以成功了。

3.安装pyrealsense2：pip install pyrealsense2
