`gpustat` is no more a zero-dependency script and now depends on some packages. Please install using pip.
- Use `nvidia-ml-py` bindings and `psutil` to replace command-line call of `nvidia-smi` and `ps` (20, Thanks to Stonesjtu).
- A behavior on pipe is changed; it will not be in color by default, use `--color` explicitly. (e.g. `watch --color -n1.0 gpustat --color`)
- Fix a bug in handling stale-state or zombie process (16)
- Include non-CUDA graphics applications in the process list (18, Thanks to kapsh)
- Support power usage (13, 28, Thanks to cjw85)
- Support `--debug` option
