Xgboost 在尝试导入时抛出错误

Question

我有一个使用 xgboost 的项目。我们现在将项目转移到容器。但是使用pip安装后，它抛出以下错误：

Traceback (most recent call last):
  File "restart_db.py", line 5, in <module>
    from autoai.core.providers import GlobalEnrichmentProvider

    'Error message(s): {}\n'.format(os_error_list))
xgboost.core.XGBoostError: XGBoost Library (libxgboost.so) could not be loaded.
Likely causes:
  * OpenMP runtime is not installed (vcomp140.dll or libgomp-1.dll for Windows, libgomp.so for UNIX-like OSes)
  * You are running 32-bit Python on a 64-bit OS
Error message(s): ['libgomp.so.1: cannot open shared object file: No such file or directory']

我检查了我的 python 和我的 ubuntu 都是 64 位的，然后运行： apt-get update && apt-get install -y libaio1

确保该包在那里（我在某处读到这可能是问题所在）-但它仍然会引发相同的错误。

我已经坚持了一段时间了，我会很感激任何帮助。

我遇到了同样的错误lightGBM，为了解决我运行的问题：

apt-get install libgomp1 

lightGBM这是在调用任何代码之前必需的。对我来说，错误是在取消lightGBM模型时发生的，而不是在导入时发生的lightGBM。
