Subject: [PATCH] Compatibility with python 3.7.6 (#1368)

The urlparse function has changed.

Old versions:
```python
>>> urlparse('localhost:8500')
ParseResult(scheme='', netloc='', path='localhost:8500', params='', query='', fragment='')
```

3.7.6:
```python
>>> urlparse('localhost:8500')
ParseResult(scheme='localhost', netloc='', path='8500', params='', query='', fragment='')
```
