ImportError：无法从“tensorflow.python.keras.applications”导入名称“resnet”

Question

我一直在尝试实现this colab code，但在训练部分代码时遇到了这个错误。

（python版本Python 3.7.12和tensorflow版本1.14。）

!python3 /content/gun_detection/models/research/object_detection/model_main.py \
    --pipeline_config_path={config_path + pipeline_file} \
    --model_dir={model_dir} \
    --alsologtostderr \
    --num_train_steps={num_steps} \
    --num_eval_steps={num_eval_steps}

我收到此 ImportError 消息：

Answer 1

关注此document。 : tf.keras.applications.resnet 没有resnet。

你可以试试：

from tf.keras.applications.resnet import ResNet50

Answer 2

您可以在这里查看Tensorflow Library。

Tensorflow 1.14 没有resnet。 正确的导入是：

from tensorflow.keras.applications import resnet50
