I can confirm that the same error also occurs using pip:

# pip3 install --upgrade git+git://github.com/vertica/Vertica-ML-Python.git

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-fvn5_nus/

At my company we use docker to create our Jupyter notebook environments and fixing this issue would greatly simplify installation of the package. I see the same error as rootchina when I invoke the setup.py script directly.

The quick workaround is deleting package_dir={'':'vertica_ml_python'}, in setup.py file.
