I’m trying to install nvcaffe with the below link, but errors occurred when I execute make all -j4
https://www.nvidia.cn/object/caffe-installation-cn.html

Here is the errors prompts:

Is there a guideline to install caffe or NVcaffe on px2? thank you.

Dear zew_wang,

Can I know why you want to install Caffe or NVcaffe on DPX2?
Because DPX2 is a platform suitable for deployment rather than training. Therefore, it is a good system to use the trained model to refer to using TensorRT. Thanks.

Dear Steve

I want to train the model with caffe, since training on the DPX2 will take fewer time than on my pc.

Does PX2 support any deep learning framework that I can training on? Thanks.

Dear zew_wang,

The link below may help. Thanks.

Hi Steve, I have got caffe installed on dpx2 and I’m training a model base on VOC dataset.

The training process is quite slow, even slower than my pc(GTX 1070)

When I set the batchsize to 8, it will out of memory.

I’m curious about that, Why?

Dear zew_wang,

I think this is expected behavior. Please check GTX1070 spec and dGPU spec on DPX2.
GTX 1070 : https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1070-ti/
dGPU in DPX2 : ./deviceQuery in /NVIDIA_CUDA-9.0_Samples/1_Utilities/deviceQuery$ on DPX2. Thanks.
