Picomon 0.2.0: From AMD Crash Fix to GPU Monitoring That Doesn’t Suck

I built picomon because nvtop kept crashing on my AMD rigs with assertion errors. Earlier this month, I whipped up a Python script with an LLM that parsed amd-smi output. It was ugly. It worked. I called it picomon.

Era 1: The Crash

I was training a 7B model on AMD MI200s. nvtop worked fine on NVIDIA. On AMD? Random crashes, assertion failures, zero visibility into memory usage. I needed something that just worked.

Era 2: The Glow-Up

Then I discovered Textual. If you haven’t used it, Textual is what happens when a Python developer gets bored of building web apps and decides terminal UIs should be beautiful. I rewrote picomon from scratch.

What 0.2.0 Actually Does

• Multi-vendor support: AMD (ROCm), NVIDIA (nvidia-smi), Apple Silicon in one tool
• Textual TUI: Live-updating dashboard with memory, utilization, temperature, power draw
• Rig cards: Navigate to a shareable summary of your setup. Mine shows:

• Lightweight: No GUI dependencies, installs with pip, runs in a tmux session

The Rig Card Flex

The rig card feature is pure ego. I have a group chat with other ML engineers. We share benchmarks, model configs, and now—server specs. Navigate to it with a quick shortcut, copy the ASCII art, paste it anywhere.

The Technical Bits

The original script used amd-smi --json and parsed the output. The Textual version uses Python’s asyncio to poll metrics every 3 seconds and renders with Rich’s layout engine. The Apple Silicon support was added because I wanted the same tool I use on servers to work on my Mac.

Why This Matters

Most GPU monitoring tools are vendor-locked or bloated. picomon is what you run in a tmux session on a headless server and forget about. The 0.2.0 release just makes it pretty.

Install it: pip install picomon

Now back to training models.
