Question

我不熟悉使用python和conda（以及Linux），并且在通过python 3.9环境运行Jupyter笔记本时遇到了一些麻烦。我注意到基本的3.8.5环境可以正常工作（并允许我打开Jupyter 6.1.4），但是我不确定为什么。我已经通过conda update conda和conda update anaconda更新了anaconda和conda并得到了相同的

# All requested packages already installed.

在anaconda-navigator GUI中，当我尝试使用py39环境并在Jupyter上单击“安装”时，我注意到它尝试安装Jupyter 6.0.3版，并且我也得到了this error.

我还尝试将pykernel安装到我的环境中（不确定是否会做任何事情来解决我的问题）

$conda install ipykernel

我假设这就是Jupyter无法安装笔记本的原因。我真的是新手，所以如果需要我提供更多详细信息，请告诉我。我不太了解这个问题，也找不到类似的东西。

Answer 1

您可以按照以下步骤操作：

this.bestMove = findBestMove(board);
conda create -n py39 python=3.9
pip3 install --upgrade pip
转到anaconda提示
激活py39
运行jupyter-notebook
根据机器更改路径后运行：pip3 install jupyter
运行：anaconda提示符下的jupyter-notebook
在Jupyter笔记本上检查Python版本。

Answer 2

基于Pushpendra Singh Nathavat的回应，我尝试的方法是：

// CallExtensionFunction.java
package com.example.groundup;

public class CallExtensionFunction {

    public static void main(String[] args) {

        MyModel myModel = new MyModel();

        int bar = MyModelKt.bar(myModel);

        System.out.println(bar);
    }
}


// MyModell.kt
package com.example.groundup

fun MyModel.bar(): Int {
    return this.name.length
}

class MyModel() {
   val name = "Hugo"
}

您可以使用以下方法检查笔记本中的Python版本：

conda create -n py39 python=3.9 -y 
conda activate py39
pip install jupyter
jupyter notebook

Answer 3

您必须在终端中编写三个代码。

conda create -n py39 python = 3.9
pip3 install --upgrade pip
pip3安装jupyter

无法使用python 3.9 env运行Jupyter Notebook
