Python 3.6 Local Mode breaks due to usage of pathlib.Path and sqlite3

[HeardACat]

Expected Behavior

Python 3.6 in local mode works when following the quickstart

Current Behavior

Unable to follow quickstart due to the error as shown below

Steps to reproduce

1. Create a Python 3.6 environment. E.g. conda create --name=feast36 python=3.6
2. Install feast and other deps pip install feast
3. Follow the quickstart

When running the quick start it will fail with the following msg.

(feast36) ➜  temp_feat$ feast init feat1

Creating a new Feast repository in /home/user/Documents/temp_feat/feat1.

(feast36) ➜  temp_feat$ cd feat1
(feast36) ➜  feat1$ feast apply

Specifications

• Version: 3.6
• Platform: Ubuntu 20.04, also tested on Ubuntu 18.05
• Subsystem:

Possible Solution

The sqlite3 issue is resolved in Python 3.7 as shown here:
https://bugs.python.org/issue33496

A solution could be to add self._db_path = str(self._db_path) or similar in the infra/local.py file

I couldn't find a similar issue - in the case its resolved in an upstream commit...
