如何在macOS virtualenv中正确安装xgboost python包装器？

Question

Under virtualenv, I'm trying to install python wrapper using official installation guide . When I did

sudo python setup.py install

I got errors:

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.

In this post https://stackoverflow.com/a/41061466 , the guy advised remove "include_package_data=True" from setup.py . I did that, then xgboost has been successfully installed, ie python -c "import xgboost; print(xgboost.__version__)" outputs 0.6.

Nevertheless, when I execute it in folder that is different from xgboost_root_dir/python-package/ , I get:

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'

How to resolve this issue?

Answer 1

As a workaround, I did:

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

Answer 2

您只需注释这些行，然后一切正常！
