Compiling SSD (Single Shot Detection) on Jetson TX1

We’re compiling SSD for the Jetson TX1 per the instructions on Realtime Object Detection with SSD on Nvidia Jetson TX1.

We get the following error.

We’ve looked at

https://devtalk.nvidia.com/default/topic/974832/nvcc-compilation-errors-on-24-2-l4t-platform-tx1/

and

https://devtalk.nvidia.com/default/topic/996726/?comment=5096488, where we upgraded eigen to 3.3 using the libeigen3-dev_3.3-beta1-2_all.deb file.

Nothing seems to work so far.

Ubuntu 16.04
JetPack: # R24 (release), REVISION: 2.1

Any help would be appreciated.

Thank you!

Hi
Do you build it on the Desktop or TX1 system?

Build it on the TX1.

I think it might be related to using OpenCV 3.1 with Neon turned on, I am going to try it with a fresh install of Open CV 3.1 with Neon turned off…

Note: This configuration does not set the ENABLE_NEON parameter.

On the TX1/TX2, the ENABLE_NEON parameter is ignored. ARM64/ aarch64 is assumed to have NEON support. Some of the earlier ARM architectures did not support NEON, others did hence the flag.

Hi,

Thanks for your feedback.
Just confirmed that caffe-ssd can be successfully built with opencv3.2.0.

Sharing my opencv cmake configure:

cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="5.3" -D CUDA_ARCH_PTX="" -D WITH_GSTREAMER=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

This answer doesn’t help for my problem which is exactly same as the question. (I also use TX1 board)

Does anyone solve this problem?

Thanks…

Hi,

Thanks for your question.

This error caused by using an OpenCV with Neon turned on. Please make sure your opencv is built with valid configuration.

If you are not sure which cmake options should be used, please use the configuration posted in #6.
We have verified that ssd works properly with this opencv options.

Please let us know the results.
If you still meet error with above steps, please also share your opencv cmake command.

Thanks.

Hi, AastaLLL

I’m still struggling with the problem, and I need your help.

=opencv=

I build opencv as you mentioned above.
I checked the opencv build configuration by calling getBuildInformation().
I got the following message, so, NEON seems to be blocked because .

requested:                 NEON
disabled:                  VFPV3 NEON

=caffe-ssd=

When I build caffe-ssd, I got the following messages and build is terminated.

= Summary =
There are some problems with building caffe-ssd.
The error occurs at arm_neon.h, when NVCC starts.
How should I handle this problem?
Also, could you share your caffe-ssd make-config file?
If you need more info, I’ll post it ASAP.

Thanks.

Hi,

Thanks for your feedback. I double checked it today, caffe-ssd can be successfully compiled with the opencv cmake options mentioned in #6.

I installed opencv based on http://dev.t7.ai/jetson/opencv/ but replacing the cmake option to

cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="5.3" -D CUDA_ARCH_PTX="" -D WITH_GSTREAMER=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

Hope this helps and please let us know the results.

Thanks AastaLLL!

I solved it by changing openCV version from 3.2 to 3.1.
I don’t know why openCV 3.2 occurred some problems, but 3.1 is fine anyway.

Thanks again.

Here is what I have so far:

  1. Removed Opencv4tegra
  2. Installed Opencv 3.1 on TX1 (Had problem installing Caffe with 3.2, hence 3.1!)
  3. Got the image grabber working with opencv (python). Here is the VideoCapture input (Leopard Imaging MIPI camera):

cap = cv2.VideoCapture(“nvcamerasrc ! video/x-raw(memory:NVMM), width=(int)192, height=(int)1080,format-(string)I420,framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink”)

  1. Installed SSD

Now, how do I input the device ID to ssd_pascal_webcam.py?

Any leads will be appreciated. Thanks in advance!

Hi,

Jetson only has one GPU. It should be able to get the correct device ID. (since only device:0 is available)
Do you meet error in running SSD?

From what I remember, there was no error. It gave a blank screen. I will double check.

Thanks,
-P

Hi pnambiar,

Let’s track this issue on topic 1019911:
https://devtalk.nvidia.com/default/topic/1019911/

CUDA architecture setting: going with all of them.

For CUDA < 6.0, comment the *_50 lines for compatibility.

CUDA_ARCH := -gencode arch=compute_20,code=sm_20
-gencode arch=compute_20,code=sm_21
-gencode arch=compute_30,code=sm_30
-gencode arch=compute_35,code=sm_35
-gencode arch=compute_50,code=sm_50
-gencode arch=compute_50,code=compute_50

are you sure this part is right ? not sm_50?

Hi,

TX1 is sm_53.
TX2 is sm_62.

Please add the correct architecture into the Makefile.
Architecture information can be found here:
