Hi,
I'm trying to use a linux cluster to do basic photogrammetry. My server, node, and client are all non-GUI and in CentOS 7. There's a mounted folder accessible by server, node, and client alike. I'm using the standalone Python module on client to send instructions. I have a saved project on the mounted folder with photos already imported.
Using the client, I can process the photos locally fine, but I got "Document is empty" error after sending the same task to the server. Could you help me with this?
