我正在尝试将 pytorch 模型转换为 ONNX,以便稍后将其用于 TensorRT。我遵循以下教程https://pytorch.org/tutorials/advanced/super_resolution_with_caffe2.html,但我的内核一直死机。
这是我实现的代码。
# Some standard imports
import io
import numpy as np
from torch import nn
import torch.onnx
from deepformer.nets.quicknat import quickNAT
param = {
'num_channels': 64,
'num_filters': 64,
'kernel_h': 5,
'kernel_w': 5,
'kernel_c': 1,
'stride_conv': 1,
'pool': 2,
'stride_pool': 2,
'num_classes': 1,
'padding': 'reflection'
}
net = quickNAT(param)
checkpoint_path = 'checkpoint_epoch36_loss0.78.t7'
checkpoints=torch.load(checkpoint_path)
map_location = lambda storage, loc: storage
if torch.cuda.is_available():
map_location = None
net.load_state_dict(checkpoints['net'])
net.train(False)
# Input to the modelvcdfx
x = torch.rand(1, 64, 256, 1600, requires_grad=True)
# Export the model
torch_out = torch.onnx._export(net, # model being run
x, # model input (or a tuple for multiple inputs)
"quicknat.onnx", # where to save the model (can be a file or file-like object)
export_params=True) # store the trained parameter weights inside the model file
