Preventing Paraview Visualizer popup paraview windows on startup?

Web Support
1

I launch paraview-visualizer in a conda environment with

python -m paraview.apps.trame --trame-app pv_visualizer.app --port 1234 --data .

Visualizer itself works fine. But at start and then when loading a state file paraview windows popup. How can I avoid it?

There is a --force-offscreen-rendering argument you can use. If I have a typo in what I wrote, you can use --help to find what you are looking for.

Hello Sebastian, thank you for the hint.

But if I pass --help argument, I don’t see --force-offscreen-rendering or something similar.

python -m paraview.simple --trame-app pv_visualizer.app --help

Kitware trame

options:
  -h, --help            show this help message and exit
  --server              Prevent your browser from opening at startup
  --banner              Print trame banner
  --app                 Use OS built-in browser
  --no-http             Do not serve anything over http
  --authKeyFile AUTHKEYFILE
                        Path to a File that contains the Authentication key for clients to connect to the WebSocket. This takes precedence over '-a, --authKey' from wslink.
  --hot-reload          Automatically reload state/controller callback functions for every function call. This allows live editing of the functions. Functions located in the site-packages directories are skipped.
  --trame-args TRAME_ARGS
                        If specified, trame will ignore all other arguments, and only the contents of the `--trame-args` will be used. For example: `--trame-args="-p 8081 --server"`. Alternatively, the environment variable
                        `TRAME_ARGS` may be set instead.
  --debug               log debugging messages to stdout
  --nosignalhandlers    Prevent installation of signal handlers so server can be started inside a thread.
  --host HOST           the interface for the web-server to listen on (default: 0.0.0.0)
  -p PORT, --port PORT  port number for the web-server to listen on (default: 8080)
  --timeout TIMEOUT     timeout for reaping process on idle in seconds (default: 300s, 0 to disable)
  --content CONTENT     root for web-pages to serve (default: none)
  --authKey AUTHKEY     Authentication key for clients to connect to the WebSocket.
  --ws-endpoint WS      Specify WebSocket endpoint. (e.g. foo/bar/ws, Default: ws)
  --no-ws-endpoint      If provided, disables the websocket endpoint
  --fs-endpoints FSENDPOINTS
                        add another fs location to a specific endpoint (i.e: data=/Users/seb/Download|images=/Users/seb/Pictures)
  --reverse-url REVERSE_URL
                        Make the server act as a client to connect to a ws relay
  --ssl SSL             add a tuple file [certificate, key] (i.e: --ssl 'certificate,key') or adhoc string to generate temporary certificate (i.e: --ssl 'adhoc')
  --data DATA           Path to browse
  --plugins PLUGINS     List of distributed plugins to load

Those are pvpython options not regular python. Sorry I skipped conda environment. In the code, you could make the view offscreen, but that would require code change. With conda, you don’t have much other options unfortunately.

BTW, which OS?

I use Win11

Unfortunately for you, the only way is to use ParaView/pvpython with a venv.
