Deep learning 如何在NVIDIA Jetson Nano上将U-Net细分模型转换为TensorRT?(进程终止错误)
我用Keras(使用TF后端)训练了一个U-Net分割模型。 我试图在Jetson Nano上将其冻结的图形(.pb)转换为TensorRT格式,但该过程被终止(如下所示)。我在其他帖子上看到,这可能与“内存不足”问题有关。 众所周知,我已经有一个SSD MobileNet V2模型在Jetson Nano上运行 如果我停止systemctl,我可以使用U-Net模型进行推理,而无需将其转换为TensorRT(仅使用加载Tensorflow的冻结图模型)。当我启动systemctl时,这种方法不起作用(所以当另一个神经网络运行时),我尝试将我的U-Net分段模型转换为TensorRT,以获得它的优化版本(由于进程被终止而失败),但这可能不是正确的方法 有可能在Jetson Nano上运行两个神经网络吗?还有别的办法吗 以下是我尝试将冻结的图形转换为TensorRT的方法:Deep learning 如何在NVIDIA Jetson Nano上将U-Net细分模型转换为TensorRT?(进程终止错误),deep-learning,computer-vision,embedded,tensorrt,nvidia-jetson-nano,Deep Learning,Computer Vision,Embedded,Tensorrt,Nvidia Jetson Nano,我用Keras(使用TF后端)训练了一个U-Net分割模型。 我试图在Jetson Nano上将其冻结的图形(.pb)转换为TensorRT格式,但该过程被终止(如下所示)。我在其他帖子上看到,这可能与“内存不足”问题有关。 众所周知,我已经有一个SSD MobileNet V2模型在Jetson Nano上运行 如果我停止systemctl,我可以使用U-Net模型进行推理,而无需将其转换为TensorRT(仅使用加载Tensorflow的冻结图模型)。当我启动systemctl时,这种方法不
trt_graph = trt.create_inference_graph(
input_graph_def=frozen_graph_gd, # Pass the parsed graph def here
outputs=['conv2d_24/Sigmoid'],
max_batch_size=1,
max_workspace_size_bytes=1 << 32, # I have tried 25 and 32 here
precision_mode='FP16'
)
如果模型有不受支持的层,则无法转换为张量RT。如果是这种情况,使用tensorflow的版本或TRT可以产生结果,因为该版本可以处理不受支持的层(它们将由tensorflow与您的tens rt转换层一起处理) 希望答案接近你的问题。张量rt是一个混乱的生态系统
