`NotADirectoryError` when starting server after installing from source

Hi,

Using Python 3.6.1 |Anaconda custom (64-bit):

git clone https://github.com/facebookresearch/visdom.git
cd visdom
python setup.py install
python -m visdom.server

returns:

Traceback (most recent call last):

    "__main__", mod_spec)

It was working when I installed using pip, but then I can’t run example/demo.py because there was no Visdom.check_connection.

@pltrdy I’m investigating what might’ve happened now

Alright I think I’ve come to the core of the problem, going to push a fix soon. After moving to setuptools from distutils the installation flow from source is a little different from what is currently in the docs.

If you want to get ahead of the fix, change zip_safe in setup.py to False, then use easy_install . from within the visdom directory rather than pip
