gpu-memory-profiler 0.2.3.post1

Deprecated package alias for Stormlog. Install 'stormlog' instead.

Stormlog

Deprecated PyPI distribution notice: gpu-memory-profiler is kept only as a migration alias. Install stormlog instead with pip install stormlog. Python imports remain gpumemprof and tfmemprof, and the TUI command remains stormlog.

Interactive Textual dashboard with live monitoring, visualizations, and CLI automation.

A production-ready, open source tool for real-time GPU memory profiling, leak detection, and optimization in PyTorch and TensorFlow deep learning workflows.

Why use Stormlog?

• Prevent Out-of-Memory Crashes: Catch memory leaks and inefficiencies before they crash your training.
• Optimize Model Performance: Get actionable insights and recommendations for memory usage.
• Works with PyTorch & TensorFlow: Unified interface for both major frameworks.
• Beautiful Visualizations: Timeline plots, heatmaps, and interactive dashboards.
• CLI & API: Use from Python or the command line.

Features

• Real-time GPU memory monitoring
• Memory leak detection & alerts
• Interactive and static visualizations
• Context-aware profiling (decorators, context managers)
• CLI tools for automation
• Data export (CSV, JSON)
• CPU compatibility mode

Quick Start

PyTorch Example

from gpumemprof import GPUMemoryProfiler
profiler = GPUMemoryProfiler()

def train_step(model, data, target):
    output = model(data)
    loss = ...
    loss.backward()
    return loss

profile = profiler.profile_function(train_step, model, data, target)
summary = profiler.get_summary()
print(f"Profiled call: {profile.function_name}")
print(f"Peak memory: {summary['peak_memory_usage'] / (1024**3):.2f} GB")

TensorFlow Example

from tfmemprof import TFMemoryProfiler
profiler = TFMemoryProfiler()
with profiler.profile_context("training"):
    model.fit(x_train, y_train, epochs=5)
results = profiler.get_results()
print(f"Peak memory: {results.peak_memory_mb:.2f} MB")

Documentation

Start at the docs home page and follow the same structure locally or when hosted:

• Documentation Home (local)
• Documentation Home (hosted)

Key guides:

• CLI Usage
• CPU Compatibility
• Compatibility Matrix (v0.2)
• GPU Setup (drivers + frameworks)
• Testing Guides, TensorFlow
• Example Test Guides (Markdown)
• Terminal UI (Textual)
• In-depth Article
• Example scripts
• Launch scenario scripts

Launch QA Scenarios (CPU + MPS + Telemetry + OOM)

Run the capability matrix for a launch-oriented smoke pass:

python -m examples.cli.capability_matrix --mode smoke --target both --oom-mode simulated

Run the full matrix (includes extra demos):

python -m examples.cli.capability_matrix --mode full --target both --oom-mode simulated

Key scenario modules:

python -m examples.scenarios.cpu_telemetry_scenario
python -m examples.scenarios.mps_telemetry_scenario
python -m examples.scenarios.oom_flight_recorder_scenario --mode simulated
python -m examples.scenarios.tf_end_to_end_scenario

Terminal UI

Prefer an interactive dashboard? Install the optional TUI dependencies and launch the Textual interface:

pip install "stormlog[tui]"
stormlog

The TUI surfaces system info, PyTorch/TensorFlow quick actions, and CLI tips. Future prompt_toolkit enhancements will add a command palette for advanced workflows—see docs/tui.md for details.

Overview, PyTorch, and TensorFlow tabs inside the Textual dashboard.

CLI & Actions tab with quick commands, loaders, and log output.

Need charts without leaving the terminal? The new Visualizations tab renders an ASCII timeline from the live tracker and can export the same data to PNG (Matplotlib) or HTML (Plotly) under ./visualizations for deeper inspection. Just start tracking, refresh the tab, and hit the export buttons.

Need fast distributed triage? The Diagnostics tab loads live telemetry or merged artifacts (JSON, CSV, diagnose directories), then renders per-rank delta/gap diagnostics, timeline comparisons, and first-cause indicators (earliest + most severe). It also handles partial rank availability and supports rank filters like 0,2,4-7.

Distributed Diagnostics tab workflow (live + artifact inputs, rank table, timeline compare, anomaly summary).

The PyTorch and TensorFlow tabs now surface recent decorator/context profiling results as live tables—with refresh/clear controls—so you can review peak memory, deltas, and durations gathered via gpumemprof.context_profiler or tfmemprof.context_profiler without leaving the dashboard.

When the monitoring session is running you can also dump every tracked event to ./exports/tracker_events_<timestamp>.{csv,json} directly from the Monitoring tab, making it easy to feed the same data into pandas, spreadsheets, or external dashboards.

Need tighter leak warnings? Adjust the warning/critical sliders in the same tab to update GPU MemoryTracker thresholds on the fly, and use the inline alert history to review exactly when spikes occurred.

Need to run automation without opening another terminal? Use the CLI tab’s command input (or quick action buttons) to execute gpumemprof / tfmemprof commands in-place, trigger gpumemprof diagnose, run the OOM flight-recorder scenario, and launch the capability-matrix smoke checks with a single click.

CPU Compatibility

Working on a laptop or CI agent without CUDA? The CLI, Python API, and TUI now fall back to a psutil-powered CPUMemoryProfiler/CPUMemoryTracker. Run the same gpumemprof monitor / gpumemprof track commands and you’ll see RSS data instead of GPU VRAM, exportable to CSV/JSON and viewable inside the monitoring tab. PyTorch sample workloads automatically switch to CPU tensors when CUDA isn’t present, so every workflow stays accessible regardless of hardware.
