Description

Is there a mechanism to detect if a program crushes? Like segmentation default or cudaRuntime Error in PyTorch, so that it can pass such info onto the screen.

Research direction
Investigate how visdom currently handles errors from Python programs, particularly segmentation faults. The feature would require implementing a signal handler (e.g., for SIGSEGV) in the Python server process and establishing a mechanism (likely WebSockets) to push the error message to the web client. Key files to examine include the server's main loop and the WebSocket handler code.
