parser.add_argument("--max-jobs", type=int, help="Maximum number of concurrent 'generate' commands", default=1)
可以看出–gpu默认是0，如果有多张卡我们可以指定某个卡进行操作。
另外：所以启动注意事项：如果是docker启动那么可以
docker run -d –gpus ‘“device=2”’文章来源：https://www.toymoban.com/news/detail-512483.html
另外注意启动模式：文章来源地址https://www.toymoban.com/news/detail-512483.html
if [ "${RUN_MODE}" = "OPTIMIZED" ] ; then
echo "Running OPTIMIZED mode"
RUN_ARGS="--gfpgan-cpu --esrgan-cpu --optimized"
elif [ "${RUN_MODE}" = "OPTIMIZED-TURBO" ] ; then
echo "Running OPTIMIZED-TURBO mode"
RUN_ARGS="--gfpgan-cpu --esrgan-cpu --optimized-turbo"
elif [ "${RUN_MODE}" = "GTX16" ] ; then
echo "Running GTX16 mode"
RUN_ARGS="--precision full --no-half --gfpgan-cpu --esrgan-cpu --optimized"
