Question

是否可以向Azure Data Analytics Analytics添加比pandas，numpy和numexpr更多的Python库？具体来说，我们需要在使用U-SQL处理NetCDF文件时使用xarray，matplotlib，Basemap，pyresample和SciPy。

Answer 1

假设libs与已部署的Python运行时一起使用，请尝试将库上载到ADLS中的某个位置，然后在脚本中使用DEPLOY RESOURCE "path to lib";。我没有尝试过，但它应该有效。

Answer 2

指的是同样的问题，它尝试了以下导致错误的方法：

下载原始ExtPy程序集。
使用UsqlPythonDeployPackage.zip中的python.exe（和pip）安装新模块
通过更换旧组件来上传新组件。

重新运行与原始ExtPy一起使用的脚本（不使用其他模块）会导致以下错误：
