Question

在virtualenv下，我正在尝试使用official installation guide安装python包装器。当我做的时候

sudo python setup.py install

我收到了错误：

error: Error: setup script specifies an absolute path:

    /Users/dmitry/dev/mlenv/xgboost/xgboost/python-package/xgboost/../../lib/libxgboost.so

setup() arguments must *always* be /-separated paths relative to the
setup.py directory, *never* absolute paths.

在这篇文章https://stackoverflow.com/a/41061466中，该人建议从"include_package_data=True"删除setup.py。我做到了，然后成功安装了xgboost，即python -c "import xgboost; print(xgboost.__version__)"输出0.6。

然而，当我在与xgboost_root_dir/python-package/不同的文件夹中执行时，我得到：

python -c "import xgboost; print(xgboost.__version__)"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/dmitry/dev/mlenv/lib/python3.6/site-packages/xgboost-0.6-py3.6.egg/xgboost/__init__.py", line 21, in <module>
    with open(VERSION_FILE) as f:
FileNotFoundError: [Errno 2] No such file or directory: '/Users/dmitry/dev/mlenv/lib/python3.6/site-packages/xgboost-0.6-py3.6.egg/xgboost/VERSION'

如何解决此问题？

Answer 1

作为解决方法，我做了：

import sys
sys.path.append('<your-path-here>/xgboost/python-package')

Answer 2

你可以只评论这些行，然后就可以正常工作了！
