jetson nano not enough memory

[giahuytn]

hello all,
I tried to run detection.ipynb on jetsion nano model B1 (jetpack: 4.5 b129 and TF: 1.15) . It threw error: memory not enough when create inference

trt_graph = trt.create_inference_graph(
    input_graph_def=frozen_graph,
    outputs=output_names,
    max_batch_size=1,
    max_workspace_size_bytes=1 << 25,
    precision_mode='FP16',
    minimum_segment_size=50
)

how can i fix this?
thanks,
