尝试导入时，Xgboost会引发错误

Question

我有一个使用xgboost的项目。我们现在将项目转移到容器。但是在使用pip安装它之后，它会抛出以下错误：

Traceback (most recent call last):

    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，然后运行：apt-get update && apt-get install -y libaio1

为了确保包存在（我在某处读到这可能是问题） - 但它仍然会抛出相同的错误。

我已经坚持了一段时间，并会感激任何帮助。

我和lightGBM有同样的错误，为了解决我遇到的问题：

apt-get install libgomp1 

在调用任何lightGBM代码之前，这是必需的。在解开lightGBM模型时出现错误，而不是在导入lightGBM时。
