无法在 pyspark 中导入 pyarrow

Question

我正在尝试将 pyarrow 与 pyspark 一起使用。但是当我尝试执行时

import pyarrow

我收到以下错误

    In [1]: import pyarrow
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

我尝试在 conda 环境中安装 pyarrow，降级到 python 3.6 但没有成功。

有人有任何建议来解决这个问题吗？

看起来 PyArrow 没有正确安装。因此，请尝试清理旧包，然后使用以下命令再次安装 pyarrow，

   {{ conda install -c conda-forge pyarrow }}
