Python uv commands

• uv init dir_name will create a new python project
  • uv init . in an existing project directory
• uv run script.py will run script.py. No need to activate venv, uv will take care of it
• uv add lib_name will pull lib_name from pypi and add it to project
• uv remove lib_name will remove lib_name from the env
• uv lock will generate a lockfile
• uv sync will make the venv in sync with lockfile, installing and removing as required
• uv pip install -r requirements.txt in an existing project directory

Aspect	On-Policy	Off-Policy
Definition	Learns the value function for the policy being used for action selection	Can learn about a different policy than the one being used for action selection
Policy Updating	Uses the same policy for both learning and action selection	Can use different policies for learning and action selection
Data Collection	Collects data using the current policy	Can use data collected from any policy
Exploration	Typically requires a balance between exploration and exploitation	Can learn from data collected u

In order to check similarity between 2 vectors, we can check the distance between them. There are a few different metrics to measure distance between 2 vectors.

import numpy as np

1. Cosine similarity

Measures the angle between 2 non-zero vectors. It ranges between $[-1, 1]$ $$cos (\theta) = \frac{\vec{p} \cdot \vec{q}}{||p|| \text{ } ||q||}$$

def cosine_similarity(p, q):
