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 OSesMac OSX users: Run `brew install libomp` to install OpenMP runtime.* You are running 32-bit Python on a 64-bit OSError 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
