# # Orchestrate a Multi-Agent System
|
||
#
|
||
# In this notebook, we will make a multi-agent web browser: an agentic system with several agents collaborating to solve problems using the web!
|
||
#
|
||
# It will be a simple hierarchy, using a `ManagedAgent` object to wrap the managed web search agent:
|
||
# ```
|
||
# +----------------+
|
||
# | Manager agent |
|
||
# +----------------+
|
||
# |
|
||
# _________|______________
|
||
# | |
|
||
# Code interpreter +--------------------------------+
|
||
# tool | Managed agent |
|
||
# | +------------------+ |
|
||
# | | Web Search agent | |
|
||
# | +------------------+ |
|
||
# | | | |
|
||
# | Web Search tool | |
|
||
# | Visit webpage tool |
|
||
# +--------------------------------+
|
||
# ```
|
||
# Let’s set up this system.
|
||
#
|
||
# Run the line below to install the required dependencies:
|
||
# %pip install markdownify
|
||
# %pip install duckduckgo-search
|
||
# %pip install smolagents
|
||
# %pip install agentops
|
||
# 🖇️ Now we initialize the AgentOps client and load the environment variables to use the API keys.
