导入 tensorflow 没有名为 swish 的属性的 ktrain 时面临错误

Question

在导入 ktrain 时，我收到以下错误：

AttributeError: module 'tensorflow_core.keras.activations' has no attribute 'swish'

任何人都可以帮助并告诉它如何进行吗？ 在 google colab 上也可以正常工作。

完全错误：

Answer 1

检查您用于 Tensorflow（和转换器）的版本。您可以在 GitHub 中查看此问题： https://github.com/amaiya/ktrain/issues/255

我使用 ktrain==0.25.4 和 tensorflow==2.4.1 并且一切正常。

Answer 2

好的，带有 M1 的 Mac 存在一些问题。 按照以下方法解决问题： (https://github.com/apple/tensorflow_macos/issues/48)

• Anaconda 开启新环境 卸载 tensorflow & tensorboard 如果存在

• 将 x86_64 文件夹中的所有文件从 11_0 重命名为 10_16。

• 示例：tensorflow_macos-0.1a0-cp38-cp38-macosx_10_16_x86_64.whl

在 Conda 控制台中运行下面的“用户名”替换为您的用户名：

• pip install pip wheel setuptools 缓存属性六
• 点安装 "/Users/username/Downloads/tensorflow_macos/x86_64/grpcio-1.33.2-cp38-cp38-macosx_10_16_x86_64.whl"
• 点安装 "/Users/username/Downloads/tensorflow_macos/x86_64/h5py-2.10.0-cp38-cp38-macosx_10_16_x86_64.whl"
• 点安装 "/Users/username/Downloads/tensorflow_macos/x86_64/numpy-1.18.5-cp38-cp38-macosx_10_16_x86_64.whl"
