Question

我正在尝试从nvidia的仓库here.运行该教程代码这是我的Jetson TX2上的控制台imagenet程序发生的情况：

    nvidia@tegra-ubuntu:~/jetson-inference/build/aarch64/bin$ ./imagenet-console orange_0.pjg output_0.jpg
imagenet-console
  args (3):  0 [./imagenet-console]  1 [orange_0.pjg]  2 [output_0.jpg]  


imageNet -- loading classification network model from:
         -- prototxt     networks/googlenet.prototxt
         -- model        networks/bvlc_googlenet.caffemodel
         -- class_labels networks/ilsvrc12_synset_words.txt
         -- input_blob   'data'
         -- output_blob  'prob'
         -- batch_size   2

我没有在Jetson板上安装Caffe，因为本教程明确指出不需要它。我不确定如果TRT可以正确缓存，则空权错误是否会得到解决。有什么想法吗？

Python 2.7
CUDA 9.0
TensorRT 4.0

Answer 1

公司防火墙阻止了模型的正确下载。手动下载模型并将其放在networks文件夹中即可解决问题。

尝试在Jetson TX2上运行nvidia的教程代码时，为什么层权重为null，而TRT找不到缓存？
