People with poor memory (self-introduction B)
I operated Miniconda after a long time, but I forgot many things, so I will leave a note for myself.
Windows 10 Anaconda3 installed Miniconda installed PyCharm installed
There is an Anaconda Prompt (Anaconda 3), but this is not the case. There is no Miniconda Prompt, so launch a normal command prompt. Press the Windows button, type cmd, and then type Enter.
At the prompt, type:
C:\Users\[username]\Miniconda3\Scripts\activate.bat
The display changes as follows
(base) C:\Users\[username]>
By default, the virtual environment called base is activated.
conda info -e
Make sure there is an environment created with Miniconda in the list.
conda activate [Virtual environment name]
Notes on building your own Miniconda environment --Qiita
conda create -n [New virtual environment name] python=3.6
After checking, enter the new environment
conda info -e
conda activate [New virtual environment name]
like conda install numpy
