Memory size frame count mismatch

General

Hello there

I recently received the Raspberry Pi PCIe Accelerator Module with the Hailo-8L and was able to run the examples from the rpi5-examples and the Hailo Application Code Examples (GitHub - hailo-ai/Hailo-Application-Code-Examples). However, suddenly I get the an error when running any of the examples from Hailo Application Code Examples. This specific error happens when running the object detection example. I downloaded the correct hef for the Hailo-8L from the model zoo repository.

[HailoRT] [error] CHECK failed - Memory size of vstream yolov7/input_layer1 does not match the frame count! (Expected 1228800, got 0)

I can successfully run the hef using hailort-cli run. Does anybody have any pointers to what I am doing wrong?

Hey @funs

Welcome to Hailo Community.

is this the python or CPP examples ?
Please add the exact application you are running and make sure that the repo is updated , if you are using python on the rpi5 ( hailo_platform) it is not yet supported , will be enabled soon.

Regards

Hello Omri

Thank you for your response. Yes, I was indeed trying to run the python examples. I was able to build and run the C++ examples, which are working fine.

I look forward to Python support on the Pi 5 and will be using the C++ API for my stuff.

Thanks, kind regards
Stefan

I am also facing the same problem. Earlier the example code from GitHub - hailo-ai/Hailo-Application-Code-Examples was working for object-detection python but now suddenly giving the same error, I am also using Hailo-8L

[HailoRT] [error] CHECK failed - Memory size of vstream ssd_mobilenet_v1/input_layer1 does not match the frame count! (Expected 270000, got 0)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INVALID_ARGUMENT(2)

can any one help?

Hi @jamesbonr123,
Which hailort version are you using?

Hi @nina-vilela
I am using v4.18.0 version of hailort

Hi @jamesbonr123,

We believe that the issue was fixed. Could you give it a try with the updated code?

I have this error too. I work on raspberry Pi 5 and installed hailort, pcie driver and python API package for python 3.11 with version 4.18 manuallly.
On raspberry both hailortcli benchmark ~/yolov8n.hef and running the model from python API works (on tracker hailo code example).

The problem occurs when I run the code inside docker container (I installed hailort==4.18 and python API package for python 3.10 there).
user@docker:~$ hailortcli benchmark hailo/yolov8n.hef works but running the model through the python API does not. Is there anything I can do to fix this?

The problem was that I used incorrect version of numpy (above > 2.0) whereas it is required to run it with numpy==1.23.3

Thanks for letting us know the solution. We will consider adding a numpy version requirement.
