A simple tool to show specified number of GPUs with desired memory to Tensorflow
A simple tool to expose only specified number of GPUs with desired memory to Tensorflow (and a few more apps, read further). This tool queries GPU free memory values using
nvidia-smi and assigns
CUDA_VISIBLE_DEVICES environment variable based on the specified memory and number of GPUs to expose, to expose specific GPUs. Apps such as
tensorflow-gpu use this information and utilize only the GPUs that are exposed. If your app does not make use of
CUDA_VISIBLE_DEVICES, then this is probably not what you would need.
pip install mask-gpu
To show available GPUs info
mask-gpu --info # Outputs the following # Finding GPUs with a minimum of 1024MiB free memory... # GPUs available: 6 -> [0, 1, 4, 5, 6, 7]
mask-gpu to expose 1 GPU (with a minimum of 1024MiB free memory)
`mask-gpu` # Remember to wrap mask-gpu in ` symbol # Or else mask-gpu will print the command # and you will have to manually execute it
mask-gpu seraches for GPUs with atleast 1024M free memory and allots 1 GPU
mask-gpu --info --min_memory 1024 # mask-gpu -i -m 1024 <--- Same as above # Info does not execute any commands `mask-gpu --expose 1 --min_memory 1024` # `mask-gpu -e 3 -m 1024` <--- Same as above # Remember to wrap mask-gpu in ` symbol
You can specify your own options using the above as the template
Unmask all (Revert)
To unmask all GPUs, i.e, to revert to what it was before using
`mask-gpu --unmask-all` # `mask-gpu -u` <--- Same as above # Remember to wrap mask-gpu in ` symbol
NOTE: This command will clear
CUDA_VISIBLE_DEVICES and hence it will be erased when executing the above command
