初始 resnet v2 模型(tensorflow)
(来自 https://github.com/tensorflow/models/tree/master/research/slim)
运行脚本:
mmconvert -sf tensorflow -iw inception_resnet_v2_jsy.pb --inNodeName input --inputShape 299,299,3 --dstNodeName InceptionResnetV2/Logits/Logits/BiasAdd -df pytorch -om tf_to_pytorch_inception_resnet_v2.pth
你好，
我试图将 tensorflow 模型(inception resnet v2 的 pb 文件)转换为 pytorch 模型以使用 mmdnn。
我使用 pb 文件 (resnet_v1_50, inception_v3) 获得了 2 个模型的成功结果，但是当我尝试转换 inception_resnet_v2 时，出现以下错误。
有没有人有一些想法来解决它们或解释这些问题？

最佳答案
而是 mmconvert您可以使用 tf2onnx将 Tensorflow 转换为 ONNX 的包。然后你可以加载 .onnx模型并将其另存为 .pth .
