gpustat

Just less than nvidia-smi?

NOTE: This works with NVIDIA Graphics Devices only, no AMD support as of now. Contributions are welcome!

Self-Promotion: A web interface of gpustat is available (in alpha)! Check out gpustat-web.

Quick Installation

Install from PyPI:

pip install gpustat

If you don't have root (sudo) privilege, please try installing gpustat on user namespace: pip install --user gpustat.

To install the latest version (master branch) via pip:

pip install git+https://github.com/wookayin/gpustat.git@master

NVIDIA Driver and pynvml Requirements

[!IMPORTANT] DO NOT: pip install pynvml, nor include pynvml as a dependency in your python project. This will not work.

Instead: pip install nvidia-ml-py. nvidia-ml-py is NVIDIA's the official python binding for NVML.

• gpustat 1.2+: Requires nvidia-ml-py >= 12.535.108 (#161)
• gpustat 1.0+: Requires NVIDIA Driver 450.00 or higher and nvidia-ml-py >= 11.450.129.
• If your NVIDIA driver is too old, you can use older gpustat versions (pip install gpustat<1.0). See #107 for more details.

Python requirements

• gpustat<1.0: Compatible with python 2.7 and >=3.4
• gpustat 1.0: Python >= 3.4
• gpustat 1.1: Python >= 3.6

Usage

$ gpustat

Options (Please see gpustat --help for more details):

• --color : Force colored output (even when stdout is not a tty)
• --no-color : Suppress colored output
• -u, --show-user : Display username of the process owner
• -c, --show-cmd : Display the process name
• -f, --show-full-cmd : Display full command and cpu stats of running process
• -p, --show-pid : Display PID of the process
• -F, --show-fan : Display GPU fan speed
• -e, --show-codec : Display encoder and/or decoder utilization
• -P, --show-power : Display GPU power usage and/or limit (draw or draw,limit)
• -a, --show-all : Display all gpu properties above
• --id : Target and query specific GPUs only with the specified indices (e.g. --id 0,1,2)
• --no-processes : Do not display process information (user, memory) (#133)
• --watch, -i, --interval : Run in watch mode (equivalent to watch gpustat) if given. Denotes interval between updates.
• --json : JSON Output (#10)
• --print-completion (bash|zsh|tcsh) : Print a shell completion script. See #131 for usage.

Tips

• Try gpustat --debug if something goes wrong.
• To periodically watch, try gpustat --watch or gpustat -i (#41).
  • For older versions, one may use watch --color -n1.0 gpustat --color.
• Running nvidia-smi daemon (root privilege required) will make querying GPUs much faster and use less CPU (#54).
• The GPU ID (index) shown by gpustat (and nvidia-smi) is PCI BUS ID, while CUDA uses a different ordering (assigns the fastest GPU with the lowest ID) by default. Therefore, in order to ensure CUDA and gpustat use same GPU index, configure the CUDA_DEVICE_ORDER environment variable to PCI_BUS_ID (before setting CUDA_VISIBLE_DEVICES for your CUDA program): export CUDA_DEVICE_ORDER=PCI_BUS_ID.

Python API

gpustat can also be used as a library to query GPUs from your own code:

import gpustat

stats = gpustat.new_query()   # a GPUStatCollection
stats.print_formatted()       # same output as the `gpustat` command

data = stats.jsonify()        # query result as a dict (same as `gpustat --json`)

Default display

[0] GeForce GTX Titan X | 77°C,  96 % | 11848 / 12287 MB | python/52046(11821M)

• [0]: GPU index (starts from 0) as PCI_BUS_ID
• GeForce GTX Titan X: GPU name
• 77°C: GPU Temperature (in Celsius)
• 96 %: GPU Utilization
• 11848 / 12287 MB: GPU Memory Usage (Used / Total)
• python/...: Running processes on GPU, owner/cmdline/PID (and their GPU memory usage)
