Conda 环境和 Jupyter Notebook，Python 3.9.2

问题描述

我的 Conda 环境没有出现在我的 Jupiter Notebooks 中.我已经在这里查看了所有(优秀的)对话，但它似乎不适用于 python 3.9.2.

My Conda Environments are not showing up in my Jupiter Notebooks. I've reviewed all the (excellent) dialogue here, but it doesn't appear to work for python 3.9.2.

我尝试了以下方法，但没有成功:

I tried the following, which didn't work:

conda install jupyter
conda install ipykernel
conda install nb_conda

然后当我尝试以下 conda install nb_conda_kernels 我得到以下错误:

Then when I try the following conda install nb_conda_kernels I get the following error:

Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - nb_conda_kernels -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0']

Your python: python=3.9

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

如何让我的 conda 环境在 python 3.9.2 的 jupyter 笔记本中显示?谢谢！

How can I get my conda environments to show in jupyter notebooks in python 3.9.2? Thank you!

解决方案

尝试使用 conda-forge 频道，例如:

Try using the conda-forge channel, e.g.:

$ conda install -c conda-forge ipykernel

如果这个 conda env 只是一个要添加的内核，你不需要安装 jupyter，如果这是你想做的.

And you don't need to install jupyter if this conda env is just a kernel to add, if that's what you want to do.

之后，您需要在 conda env 中运行它:

After that, you need to run this in that conda env:

$ python -m ipykernel install --user --name vanilla --display-name "Python 3 (vanilla)"

根据自己的喜好替换名称和显示名称.

Replace the name and display-name to your liking.
