python anaconda installation, environment variable upgrade and special library installation

Anaconda is a flagship python installation package, because ordinary python does not have libraries. If you need to install some important libraries, you have to download them one by one frequently, which will be very troublesome.

So this is an integrated software that can be manually upgraded in batches. Moreover, the installation of the library is also very complete and the download speed is fast.

1. After downloading from the official website, next is installed. Configure the environment variables and copy the absolute path of the installation folder to the path of the environment variable. Python cannot be started without configuring it. Of course, if you have installed other version of python, you can consider deleting the previously redundant environment variable paths.

1. Open anaconda prompt, enter conda update conda upgrade and enter conda update anaconda upgrade

2. Installation of common libraries uses conda install xxx

3. View installed libraries, conda list

4. Query and installation of special libraries, take tensorflow as an example
   anaconda search -t conda tensorflow
   anaconda show jjhelmus/tensorflow
   Then copy the last line of the prompt to install.

   The following paragraph is the download command to install the latest jupyter lab:

   conda install --channel jupyterlab
