How to install
python -m pip install --upgrade micropython_eliza
How to run
Start chat in the console:
python -m micropython_eliza.chat
See an example conversation:
python -m micropython_eliza.demo
How to use
import sys
from micropython_eliza import eliza
USERNAME_IN_CHAT = "YOU"
agent = eliza.create()
print("\n<press enter with no message to exit>")
print(f"{agent.name()}: {agent('')}")
print(f"{USERNAME_IN_CHAT}: ")
msg = sys.stdin.readline().strip()
while msg:
print(f"{agent.name()}: {agent(msg)}")
print(f"{USERNAME_IN_CHAT}: ")
msg = sys.stdin.readline().strip()
To enable printing info and debug messages, provide log handlers, e.g.:
agent = eliza.create(log_info=print, log_debug=print)
