Xgboost 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，将不胜感激任何帮助。

Answer 1

我有同样的错误lightGBM，为了解决我运行的问题：apt-get&nbsp;install&nbsp;libgomp1这是在lightGBM调用任何代码之前所必需的。我的错误是在解压lightGBM模型时发生的，而不是在导入lightGBM.

Answer 2

我在创建项目的 Docker 映像时遇到了这个问题。我使用了以下命令：RUN&nbsp;apt-get&nbsp;update&nbsp;&&&nbsp;\ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;apt-get&nbsp;-y&nbsp;--no-install-recommends&nbsp;install&nbsp;\ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;libgomp1

Answer 3

在我的 MacOS 上得到了这个，正如调试消息所暗示的那样，brew install libomp修复了它。
