I installed xgboost using "python setup.py install" from the python-package folder. All seems to be well. Conda list shows xgboost (0.6). I have attached the log file when I run "python setup.py install" xgboost_install_log.txt However, when I try to run "import xgboost as xgb" in...
在你的代码中,from xgboost import xgbclassifier中的xgbclassifier应该是XGBClassifier。Python是区分大小写的,所以正确的导入语句应该是: python from xgboost import XGBClassifier 检查xgboost库是否已安装: 打开你的Python环境(例如命令行、Jupyter Notebook或PyCharm等),然后尝试导入xgboost库来检查它是否已安装: python...
xgboost import xgboost except ImportError: xgboost = ImportError("Missing xgboost extras: `pip install functime[xgb]`") This is clever but means that the issue is raised "lazily" and can lead to issues such as #190 . I think we should revert this....
