我也有同样的问题。我的keras版本是2.7.0我的tensorflow版本是2.7.0

keras.utils.Sequence

对我不起作用。您可以使用

keras.utils.all_utils.Sequence

相反

keras==2.4.0和tensorflow==2.3.0的较新版本如下所示。
更换:

from keras.utils import np_utils

from keras import utils as np_utils

我在Keras 2.4.3中遇到了同样的错误。写作时

from keras import utils

from keras.utils import to_categorical

解决:

from keras.utils import np_utils

显然,这是从版本到版本的变化。

适用于Keras版本2.5.0和TF版本2.5.0

from tensorflow.keras.utils import to_categorical

和使用

keras.utils.to_categorical()

使用keras==2.2.4和tensorflow==1.14.0运行上述代码。
没有错误。
升级TensorFlow应该可以解决这个问题。Cheers:)

我正在运行Tensorflow 2.5.0版。通过反复试验,我发现keras.utils.np_utils可以工作。我猜他们在一些更新中把它移到了np_utils中,所以.to_categorical就可以正常工作了。
将“np_utils.to_categorical”更改为“keras.utils.np_utils.to_categorical”

我正在运行Tensorflow 2.6.0版。通过反复试验,我发现tf.keras.utils.to_categorical(y_train, num_classes)可以工作。

最新版本的Keras for Tensorflow需要更改:

tf.keras.Sequential()

keras.Sequential()
