如何在 azure 管道的 powershell 任务中使用 conda？例如以下 azure yaml：
trigger:
- master
jobs:
- job: BuildWindows
timeoutInMinutes: "0"
pool:
vmImage: 'windows-latest'
steps:
- powershell: Write-Host "##vso[task.prependpath]$env:CONDA\Scripts"
displayName: Add conda to PATH
- powershell: |
echo "Where.exe conda: "
where.exe conda
echo "Where.exe pip: "
where.exe pip
conda shell.powershell hook
conda create -y --name pyomexmeta python=3.8
conda activate pyomexmeta
displayName: test Python on windows
失败：

我现在已经尝试了很多变体，包括使用
conda init powershell有什么想法如何在 azure 上的 powershell 任务中创建并激活 conda 环境吗？
考虑使用
conda run- powershell: |
conda run -n myenv python myscript.py
displayName: "Run myscript in myenv"
但是，如果你确实需要环境，可以尝试这个：
- powershell: |
conda init powershell
conda shell.powershell hook | Out-String | Invoke-Expression
conda activate myenv
python myscript.py
displayName: "Run myscript in myenv
