突然无法调用scikit-learn、xgboost

遇到的错误包含：

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

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
    - libomp.dylib for Mac OSX
    - libgomp.so for Linux and other UNIX-like OSes
    Mac OSX users: Run `brew install libomp` to install OpenMP runtime.

  * You are running 32-bit Python on a 64-bit OS

Error message(s): ['dlopen: cannot load any more object with static TLS']

解决办法：
在脚本最开头加如下代码

# 添加在最顶部
import ctypes
import os

# 强制预加载关键库（先于任何其他导入）
# ctypes.CDLL('libgomp.so.1', mode=ctypes.RTLD_GLOBAL)
# 强制预加载 OpenMP 库
try:
    ctypes.CDLL('libgomp.so.1', mode=ctypes.RTLD_GLOBAL)
except OSError:
    # 如果上述失败，尝试指定具体路径
    ctypes.CDLL('/usr/anaconda3/envs/py37/lib/libgomp.so.1', mode=ctypes.RTLD_GLOBAL)

ctypes.CDLL('libpthread.so.0', mode=ctypes.RTLD_GLOBAL)

# 设置OpenMP环境变量
os.environ["OMP_NUM_THREADS"] = "1"
os.environ["MKL_NUM_THREADS"] = "1"
os.environ["KMP_INIT_AT_FORK"] = "FALSE"

# # 恢复导入路径（如有必要）
# import sys
# sys.path.insert(0, '/usr/anaconda3/envs/py37/lib/python3.7/site-packages')

# 以下是你的原始代码...
import sklearn  # 这行应该在预加载后
import xgboost
