根因分析

传递给 Keras 层的字符串标识符（例如 activation='relu6'）不是可识别的激活函数名称；TensorFlow 没有内置的 'relu6' 激活函数。

English

The string identifier passed to a Keras layer (e.g., activation='relu6') is not a recognized activation function name; TensorFlow does not have a built-in 'relu6' activation.

解决方案

  1. Use the correct Keras activation: change 'relu6' to 'relu' if that works, or define a custom activation function: 'def relu6(x): return tf.nn.relu6(x)' and pass it as activation=relu6.
  2. Import from tf.keras.activations: 'from tensorflow.keras.activations import relu6' if available, but note that relu6 is not in the public API; use tf.nn.relu6 directly in a Lambda layer.

无效尝试

常见但无效的做法:

  1. Use 'relu6' as a custom activation function without registering it 100% 失败

    Keras only recognizes registered activations; passing an unregistered string will always raise this error.

  2. Spell it as 'ReLU6' with different capitalization 90% 失败

    Keras activation names are case-insensitive but must match exactly; 'ReLU6' is also not a built-in activation.
