2.1 Install Python version
① First open the Prompt terminal of Anaconda and enter jupyter kernelspec list to check the installed python version. As shown in the figure below, there is only python3 that comes with Anaconda.
② Enter the conda create --name py3.6.3 python=3.6.3 command, and enter y when entering [y]/n to create a py3.6.3 virtual environment, which will install python3.6.3 to the env directory of anaconda3.
③ First make sure that the current disk is the same as the disk to be entered, enter the cd D:\11_Anaconda\envs\py3.6.3\Scripts command, and enter the Scripts folder in the py3.6.3 directory.
④ Enter conda activate py3.6.3 to activate the py3.6.3 environment, and then enter the pip install ipykernel command. A series of tools will be generated in the script directory, as shown in the figure below. (Note: When pip install ipykernel, VPN cannot be installed.)
⑤ Copy the existing project in the share/jupyter/kernels folder under the Anaconda folder and rename it to python3.6.3.
⑥ Open the json file in the folder and change Python 3 to Python 3.6.3, as shown in the figure below.
⑦ Open the Anaconda terminal again and enter jupyter kernelspec list. You can view the virtual environment where Python3.6.3 has been successfully installed.
⑧ Open Jupyter notebook again, there is Python3.6.3 option in New.
⑨ In Jupyter notebook, use python code to print the python version.
