let g:ycm_python_binary_path = '/usr/bin/python3'
```
If the value of `g:ycm_python_binary_path` is an absolute path like above it
will be used as-is, but if it's an executable name it will be searched through
the PATH. So for example if you set:
```viml
let g:ycm_python_binary_path = 'python'
```
YCM will use the first `python` executable it finds in the PATH to run
[jedi][]. This means that if you are in a virtual environment and you start vim
in that directory, the first `python` that YCM will find will be the one in the
virtual environment, so [jedi][] will be able to provide completions for every
package you have in the virtual environment.

### I can't complete python packages in a virtual environment.
This means that the Python used to run [JediHTTP][] is not the Python of the
virtual environment you're in. To resolve this you either set
`g:ycm_python_binary_path` to the absolute path of the Python binary in your
virtual environment or since virtual environment will put that Python
executable first in your PATH when the virtual environment is active then if
you set `g:ycm_python_binary_path` to just `'python'` it will be found as the
first Python and used to run [JediHTTP][].
