model.load_state_dict(state_dict)global_index 0
for name, param in model.named_parameters():print(name, param.size())print(param.data.numpy(),fileopen(fweights/{global_index}-{name}.txt, w))param.data.numpy().tofile(fweights/{global_index}-{name}.bin)global_index 1对于二进制形式的文件可以通过od -t f4 binary file name 查看其对应的浮点数值。f4表示fp32.
打印forward的中间值这么复杂是必要的
global_index 0

其中regster_hooks和以下等价不需要recursive了
def register_hooks(model):for name, layer in model.named_modules():# print(name, layer) # dump all layerslayer.register_forward_hook(hook_fn)其中nn.sequential作为一个整体目前没办法拆开来看其内部的中间值。
