将代码从 Colab 转移到 Jupyter Notebook

Question

我尝试将一些代码从 Colab 传输到 Jupyter 笔记本。

Colab中的代码是：

# Use some functions from tensorflow_docs
!pip install -q git+https://github.com/tensorflow/docs

我得到错误：

ERROR: Could not detect requirement name for 'git+https://github.com/tensorflow/docs', please specify one with #egg=your_package_name"

如果它尝试不带“！”一开始：

 pip install -q git+https://github.com/tensorflow/docs

我得到一个错误：

File "<ipython-input-11-8fda094c7d6e>", line 5
pip install -q git+https://github.com/tensorflow/docs
          ^
SyntaxError: invalid syntax

有人可以帮帮我吗？

为了找到问题，我使用 Anaconda 提示创建了一个新环境，其中包含以下几行：

conda create -n regression=3.7
conda activate regression
pip install ipykernel
python -m ipykernel install --user --name regression --display-name "regression"
conda install tensorflow-gpu
pip install keras

比我激活环境“回归”并启动jupyter notebook

我将使用的代码来自这里：here

我又试了一次：

# Use seaborn for pairplot
!pip install -q seaborn

这行得通。但是当我执行时：

# Use some functions from tensorflow_docs
!pip install -q git+https://github.com/tensorflow/docs

我现在得到错误：

" 错误：错误 [WinError 2] Das System kann die angegebene Datei nicht finden while execution command git clone -q https://github.com/tensorflow/docs 'C:\Users\MASTER~1\AppData\Local\Temp\pip-req-build -n2je0pjv' 错误：找不到命令 'git' - 您是否在 PATH 中安装了 'git'？ "

附上代码：

!pip3 install -q git+https://github.com/tensorflow/docs

我得到错误： "Der Befehl "pip3" ist entweder falsch geschrieben oder konnte nicht gefunden werden。”

如果它尝试不带“！”一开始：

你需要！如果您尝试运行 bash 命令，则在开始时。否则，Jupyter 将尝试将其作为 python 运行，这将不起作用。

您的笔记本中还有其他代码吗？当我在最新版本的 Colab 和 python3 中尝试以下代码时，它对我有用：

!pip install git+https://github.com/tensorflow/docs     

制作：

您是否尝试过重置运行时并再次运行代码？你的笔记本里还有别的吗？

没有 !不作为！用于在 Jupyter iPython 环境中调用 bash shell。

我在 Google Cloud Platform Notebook（Jupyter Lab 版本 1.1.4）中尝试了使用 Python 版本（Python 3.5.3）的命令：

!pip3 install -q git+https://github.com/tensorflow/docs --user

并且工作得很好。

!pip3 freeze | grep tensorflow
