Steps to reproduce

I upgraded from 0.15.3. I found my models are gone. After I setup model plugin, and want to set the models params, It failed. The error is below:

Hello @kelvenlaw! I'm here to help you with any issues you're experiencing. If you need help with bug fixes, have questions about the software, or want to become a contributor, I'm here to assist you.

To resolve the "PluginDaemonInternalServerError: no available node, plugin not found" error after upgrading to Dify version 1.0.0, you can try the following solutions:

Increase Python Environment Initialization Timeout: Add the following configuration line to your docker-compose.yaml file after line 560:
```
PYTHON_ENV_INIT_TIMEOUT: 320
```
This increases the Python environment initialization timeout, which should help resolve the error.
Downgrade Dify Services: If the error persists, consider downgrading the dify-api and dify-web services to version 0.15.3 in your docker-compose.yaml file. This workaround has been confirmed to resolve similar issues related to database connection problems in the plugin_daemon component in version 1.0.0-beta. The error seems to be a bug in v1.0.0-beta related to the plugin daemon's database connectivity rather than a configuration issue ^[1]^[2].

config your pip source host in docker-compose.yml//plugin_daemon//volumes ‘’‘ - ./.pip:/root/.pip ‘’’

Sorry, I don't quite understand what you mean. Do you mean to execute this command in the "docker/volumes/plugin_daemon" directory?

Try to set PLUGIN_MAX_EXECUTION_TIMEOUT in .env, the unit is second, default is 240s.

And read this thread https://github.com/langgenius/dify/issues/14736
