Solve the problem that PowerShell does not display the conda virtual environment

1. Normal execution and result of the command

PowerShell in Windows currently does not display the virtual environment of conda (as shown in Figure 1). To solve this problem, you can execute the following command.

图1PowerShell window not showing conda environment

conda init powershell

After the above command is executed, there will be a prompt to restart PowerShell to make the settings take effect (as shown in Figure 2). At this time, close PowerShell and reopen it, and the base environment of conda will be activated by default (as shown in Figure 3).

2. Instruction execution exceptions and solutions

Problem 1: CommandNotFoundError: No command 'conda conda'

Cause of the problem: The conda version is too high, just lower the conda version.
Solution: You can use the following code to downgrade the version of conda

conda install ---name base conda==指定低版本号（例如：4.6.7）

Question 2: After conda init powershell is executed, restart PowerShell and an error message appears: the file cannot be loaded

Cause of the problem: Windows 10 prohibits powershell from executing any script files by default.
Solution: Just change the execution policy of the script file.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
