如何在 Watson Studio 中安装“C”依赖项 ta-lib？

如何解决如何在 Watson Studio 中安装“C”依赖项 ta-lib？

在 IBM Cloud Watson Studio 中 Jupyter 笔记本的一个单元格中，我尝试了：

%pip install TA-Lib

导致错误：

...

在 Watson Studio 中安装“C”依赖项的方法是什么？

解决方法

ta-lib 和依赖项 libta-lib 均可从 conda-forge 获得。不幸的是，当您从 Watson Studio 笔记本使用 conda-forge 通道时，conda 需要很长时间来解决环境问题。要快速安装，请使用直接下载 URL。在撰写本文时，这将是：

!conda install https://anaconda.org/conda-forge/libta-lib/0.4.0/download/linux-64/libta-lib-0.4.0-h516909a_0.tar.bz2 https://conda.anaconda.org/conda-forge/linux-64/ta-lib-0.4.19-py37ha21ca33_2.tar.bz2
