Installing Detectron2 on CPU

[leopiney]

It happened to me when running some tools from the DensePose project that it always tried to compile the model using CUDA, which I don't have installed because I'm running some experiments on MacOS.

If you want to use CPU for inference you can add the option MODEL.DEVICE cpu to the command you are running, or add that same setting in the configuration file you are using:

MODEL:
  DEVICE: "cpu"

I also have the same error on my MacOS, please how i can use the command MODEL.DEVICE cpu or where should i write to the config file , thank you!

Check https://detectron2.readthedocs.io/tutorials/getting_started.html#inference-with-pre-trained-models i.e. in order to run inference on cpu

python demo/demo.py --config-file configs/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x.yaml \
  --input input1.jpg input2.jpg \
  --opts MODEL.WEIGHTS detectron2://COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x/137849600/model_final_f10217.pkl \
  MODEL.DEVICE cpu

If you're talking about the error build/temp.linux-x86_64-3.7/home/harshit/PycharmProjects/detectron2/detectron2/layers/csrc/vision.o: file not recognized: file format not recognized, then I solved it by downgrading binutils to 2.30-5.

You can install detectron2 on CPU and run inference.

If you google the error message, all occurrences of the message suggest a bug in binutils / elfutils . You may need to upgrade / downgrade your system or compiler toolchain.

Thanks, it worked after downgrading binutils.

Thanks @leopiney, I was able to run it on CPU using the MODEL.DEVICE option.
