Anaconda安裝配置Python虛擬環(huán)境后使用JupyterNoteBook導入新包失敗的解決方法

今天在使用Python的時(shí)候，使用Anaconda創(chuàng )建了一個(gè)虛擬環(huán)境，在Jupyter Notebook中也激活了這個(gè)虛擬環(huán)境，而且在這個(gè)環(huán)境下也安裝好了相應的包
但怎么實(shí)驗，也無(wú)法在Jupyter Notebook中成功import新包，報錯顯示No module xxx found。

實(shí)驗了各種方法均不成功，后按照下文的方式重新配置一個(gè)新的虛擬環(huán)境后，再次安裝新包成功，特此記錄一下方法。

在Windows下，為Jupyter創(chuàng )建新的kernel

1.創(chuàng )建環(huán)境

• 打開(kāi)Anaconda Prompt
• 輸入以下代碼創(chuàng )建環(huán)境

(D:\Users\拾夕\Anaconda3) C:\Users\拾夕>conda create -n KernelForJupyter python=3.6

• 得到以下結果

2.激活環(huán)境以及安裝必要的包

• 輸入以下代碼激活環(huán)境

(D:\Users\拾夕\Anaconda3) C:\Users\拾夕> activate KernelForJupyter

• 安裝 ipykernel

(KernelForJupyter) C:\Users\拾夕>conda install ipykernel

3.創(chuàng )建新的kernel

• 輸入以下代碼創(chuàng )建新的kernel

(KernelForJupyter) C:\Users\拾夕>python -m ipykernel install --name NewKernel
Installed kernelspec NewKernel in C:\ProgramData\jupyter\kernels\newkernel

• 然后就可以在Jupyter中使用了
  

4.Jupyter其他操作

• 我們通過(guò)以下代碼查看juypter kernel的其他命令

(KernelForJupyter) C:\Users\拾夕>jupyter kernelspec --help
Manage Jupyter kernel specifications.
Subcommands
-----------
Subcommands are launched as `jupyter kernelspec cmd [args]`. For information on
using subcommand 'cmd', do: `jupyter kernelspec cmd -h`.
list
    List installed kernel specifications.
install
    Install a kernel specification directory.
uninstall
    Alias for remove
remove
    Remove one or more Jupyter kernelspecs by name.
install-self
    [DEPRECATED] Install the IPython kernel spec directory for this Python

• 例如我們可以通過(guò)以下指令查看當前環(huán)境下的kernel

(KernelForJupyter) C:\Users\拾夕>jupyter kernelspec list
Available kernels:
python3 D:\Users\拾夕\Anaconda3\envs\KernelForJupyter\share\jupyter\kernels\python3
newkernel C:\ProgramData\jupyter\kernels\newkernel
