We are trying to integrate drivenet api from nvidia in autoware 1.14.0. The autoware build is working but shows the below error Driveworks exception thrown: Cannot allocate cuda pitch memory, bytes 2280618562400

terminate called after throwing an instance of ‘std::runtime_error’ what():DW Error DW_FAILURE executing DW function: dwImageStreamer_initialize(&m_streamerCPU2CUDA, &opencv_prop, DW_IMAGE_CUDA, m_sdk)

Environment setup:
Software Version = DRIVE OS Linux 5.1.6 and DriveWorks 2.2
Target Operating System = Linux
Hardware Platform = NVIDIA DRIVE™ AGX Xavier DevKit (E3550)
SDK Manager Version = 1.6.0.8170
Host Machine Version = Ubuntu 18.04
DRIVE_Software_10.0_Linux_OS_DRIVE_AGX_XAVIER

autoware version= v1.14.0
cuda version = 10.2

Dear @kagitala.varalakshmi1,
Please post your DRIVE AGX Xavier related queries to DRIVE AGX Xavier General - NVIDIA Developer Forums to get attention.

I am moving to right forum now.

Dear @kagitala.varalakshmi1,

exception thrown: Cannot allocate cuda pitch memory, bytes 2280618562400

The memory buffer size seems to be very high.

Hello @SivaRamaKrishnaNV sir

Yes Memory buffer is not enough ,how to avoid this error.

Dear @kagitala.varalakshmi1,
You can not allocate more memory than the available. May I know the image buffer size you want to allocate?

7

We are trying to run a rosbag or mp4 file, iam trying to convert into from cpu image to cuda image using drivenet function dwImageStreamer_initialize(&m_streamerCPU2CUDA, &opencv_prop, DW_IMAGE_CUDA, m_sdk);
we get this error
exception thrown: Cannot allocate cuda pitch memory, bytes 2280618562400

Dear @kagitala.varalakshmi1,
May I know the resolution/size of of cpu image?

10

Hello @SivaRamaKrishnaNV

we tried with video file of resolution 3840x2160

11

Dear @kagitala.varalakshmi1,
Could you share the used opencv_prop struct values? You need to send frame by frame to CUDA for processing. Could you refer to steps in “Simple image streamer” sample to know how to create a CPU image buffer with specific size and send to CUDA using dwImageStreamer.

12

Hi @SivaRamaKrishnaNV

dwImageProperties opencv_prop;
opencv_prop.format = DW_IMAGE_FORMAT_RGB_UINT8_PLANAR;
opencv_prop.width = m_imageWidth;
opencv_prop.height = m_imageHeight;
opencv_prop.type = DW_IMAGE_CPU;
opencv_prop.memoryLayout = DW_IMAGE_MEMORY_TYPE_PITCH;
13

Dear @kagitala.varalakshmi1,
So the buffer you are trying to transfer via Image streamer is of size 3840 * 2160 * 3* 8 bits? Could you confirm that as it is not matching to the buffer size in error.

15

Hello @SivaRamaKrishnaNV

Yes. It is not matching with buffer size in error,

16

Dear @kagitala.varalakshmi1,
It could probably a bug in Driveworks 2.2. How about testing just with DW code with latest DW release for verification of dwImagestreamer pipeline in your use case.

19

Hi @SivaRamaKrishnaNV,

Thank you for your support.

Ok. I will verify with latest Driveworks 5.6

Dear @kagitala.varalakshmi1,
For DRIVE AGX xavier platform, the last release is DW 4.0+ DRIVE OS 5.2.6.
