在运行!optuna-dashboard --port 1234 sqlite:////content/drive/MyDrive/optimization.db时，链接无效。

感谢您尝试使用optuna-dashboard。

您需要像下面这样使用`google.colab.output`：
```python
    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) # 等待服务器启动
    
    from google.colab import output
    output.serve_kernel_port_as_window(port, path='/dashboard/')

将会打印optuna-dashboard的链接。请点击以打开。

请注意，我已经将代码中的HTML实体字符（`"` 和 `'`）翻译为相应的引号。
