AttributeError: module 'pyds' has no attribute 'NVBUF_MEM_CUDA_UNIFIED'

When I’ve been using deepstream-imagedata-multistream python app in docker container (Docker Containers — DeepStream 6.1.1 Release documentation) I get the error: AttributeError: module ‘pyds’ has no attribute ‘NVBUF_MEM_CUDA_UNIFIED’.

**• Hardware Platform (Jetson / GPU) 3090
**• DeepStream Version 5.1
• JetPack Version (valid for Jetson only)
**• TensorRT Version 7.2.2.3
**• NVIDIA GPU Driver Version (valid for GPU only) 470.82
**• Issue Type: questions, bugs

Why do you run deepstream 6.0 container with deepstream 5.1 platform?

I mean container was with deepstream 5.1 (link is wrong)

Please update to the latest DeepStream version.
