我已经安装了 conda 并创建了一个 python3.7 环境。然后我安装了pandas，现在当我尝试导入pandas 时出现以下错误。

Traceback (most recent call last):
  File "/me/anaconda3/envs/py37/lib/python3.7/site-packages/pandas/__init__.py", line 29, in <module>

ImportError: /me/anaconda3/envs/py37/lib/python3.7/site-packages/pandas/_libs/interval.cpython-37m-x86_64-linux-gnu.so: invalid ELF header

The above exception was the direct cause of the following exception:

有什么想法吗？

【问题讨论】：

你是如何安装pandas的？显然，没有为您的系统正确构建 C 扩展。您使用的是 32 位还是 64 位版本的 Python？
按照熊猫安装指南中的描述使用conda install pandas。
另外，当它是活动环境时，您是否尝试在新环境中运行代码？

【解决方案1】：

原来这是conda 和pandas 的错误。

这是门票： BUG: Pandas Import is failing under Conda Python 3.7

使用conda-forge 为我解决了这个问题。
