如何在 Azure 机器学习 Juypyter Notebooks 中安装 python ta-lib 库

Question

所以我需要使用这里解释的这个 python 库：

https://medium.com/analytics-vidhya/recognizing-over-50-candlestick-patterns-with-python-4f02a1822cb5

但是当我尝试执行时：

!pip install talib 导入标签

我收到很多错误：

@phd 是对的。 TA-lib Python 库的 README.md 说

要使用 TA-Lib for python，您需要已经安装了 TA-Lib。

我刚刚创建了一个新的 AML 计算实例，并且在第一次在 VM 上手动下载、构建和安装 TA-lib 包后，能够成功导入 Python 的 TA-lib。一些步骤大约需要 5 分钟，但 YMMV

在 Azure ML 计算实例上安装。

1. 在 Jupyter Labs 中打开计算实例
2. 打开一个新终端（文件：新建：终端）
3. 键入以下命令（改编自these linux instructions）

   $ wget -c https://sourceforge.net/projects/ta-lib/files/ta-lib/0.4.0/ta-lib-0.4.0-src.tar.gz/download?use_mirror=phoenixnap -O - | tar -xz
   $ cd ta-lib/
   $ ./configure --prefix=/usr
   $ make
   $ sudo make install
   

4. 安装 TA-lib Python 包装器pip install TA-lib（由于某种原因，我不得不这样做两次）
5. 打开笔记本并使用import talib 运行单元格

。你的错误意味着你没有 TA-lib 回来
