(/home/software/anaconda3/envs/mydlenv/lib/python3.8/site-packages/tensorflow/python/keras/preprocessing/text.py) 更改keras版本就行,将2.2.0改为2.2.4 [可行方案] pip install keras==2.2.4
幸运的是,Keras有一个内置类Tokenizer,来自tensorflow.keras.preprocessing.text模块,在几行代码中可以完成所有这些工作: # Text tokenization # vectorizing text, turning each text into sequence of integers tokenizer = Tokenizer() tokenizer.fit_on_texts(X) # lets dump it to a file, so we can use it...
