Is there a way to start optuna-dashboard in Google Colaboratory?
When running !optuna-dashboard --port 1234 sqlite:////content/drive/MyDrive/optimization.db the link is invalid
Author of optuna-dashboard here. Thank you for trying to use optuna-dashboard.
You need to use google.colab.output like below:
import time
import threading
from optuna_dashboard import wsgi
import optuna
from wsgiref.simple_server import make_server
port = 1234
storage = optuna.storages.RDBStorage("sqlite:////content/drive/MyDrive/optimization.db")
app = wsgi(storage)
httpd = make_server("localhost", port, app)
thread = threading.Thread(target=httpd.serve_forever)
thread.start()
time.sleep(3) # Wait until the server startup
from google.colab import output
output.serve_kernel_port_as_window(port, path='/dashboard/')
The the link to optuna-dashboard will be printed. Please click to open.
