如何在水蟒中创造张力流的环境?

人们通常是怎么做这种事的?

编辑:被一个障碍物挡住了。在移除环境时遇到问题。找到了通往 fix 这个。得到了:

    PackagesNotFoundError: The following packages are missing from the target environment:

  -

现在尝试@b20001011建议:conda create-n myenv python=3.7。。。得到了3.8.1

...>pip install tensorflow
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

编辑结束。

编辑2:

这在今天起作用了:

(base) D:\ray\dev\ml\DC to Edge Course>conda update conda
Collecting package metadata (current_repodata.json): done
Solving environment: done

# All requested packages already installed.

编辑2结束。

我有:

(base) ...>conda env list

  conda environments:

base                     D:\Anaconda3
                      *  d:\Anaconda3

为什么我要两个?

The following packages will be DOWNGRADED:

  anaconda                                   2019.10-py37_0 --> custom-py37_1
  pycosat                              0.6.3-py37hfa6e2cd_0 --> 0.6.3-py37he774522_0

我做a时也会发生同样的事情:conda update anaconda

当我尝试更新python时,我得到:

Updating python is constricted by

anaconda -> requires python==3.7.4=h5263a28_0

If you are sure you want an update of your package either try `conda update --all` or install a specific version of the package you want using `conda install <pkg>=<version>`

done

# All requested packages already installed.

我要继续吗?

当我创建一个新环境时,它没有python。

The following packages cannot be cloned out of the root environment:
 - defaults/win-64::conda-4.8.1-py37_0
 - defaults/win-64::conda-build-3.18.9-py37_3
 - defaults/win-64::conda-env-2.6.0-1

这是怎么回事?它会对张力低吗?
