导入ktrain时遇到错误，tensorflow没有名为swish的属性

Question

导入ktrain时，我遇到以下错误：

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

有人能帮忙告诉我怎么做吗？ 同样的方法也适用于google colab

完全错误：

好的，所以M1的Mac有一些问题。 按照以下步骤解决此问题： （https://github.com/apple/tensorflow_macos/issues/48）

• Anaconda启动新环境卸载tensorflow&；张力板 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，运行以下命令，并将“用户名”替换为您的用户名：

• pip安装pip控制盘设置工具缓存属性六
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/grpcio-1.33.2-cp38-cp38-macosx_10_16_x86_64.whl”
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/h5py-2.10.0-cp38-cp38-macosx_10_16_x86_64.whl”
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/numpy-1.18.5-cp38-cp38-macosx_10_16_x86_64.whl”
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/scipy-1.5.4-cp38-cp38-macosx_10_16_x86_64.whl”
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/tensorflow_addons-0.11.2+mlcompute-cp38-cp38-macosx_10_16_x86_64.whl”
• pip安装absl py ASTUNPASE扁平缓冲区gast google_意大利面 keras_预处理opt_einsum协议张量流估计 术语彩色打字扩展件包轮张紧板护板
• pip安装 “/Users/username/Downloads/tensorflow_macos/x86_64/tensorflow_macos-0.1a0-cp38-cp38-macosx_10_16_x86_64.whl”

检查您用于Tensorflow（和transformers）的版本。您可以在GitHub中检查此问题： https://github.com/amaiya/ktrain/issues/255

我使用ktrain==0.25.4和tensorflow==2.4.1，所有的东西都工作了
