早上好keras,我想訓練LSTM分類垃圾郵件和非垃圾郵件,我碰到下面的錯誤來了:LSTM錯誤蟒蛇
ValueError: Input 0 is incompatible with layer lstm_1: expected ndim = 3, found ndim = 4
有人可以幫助我瞭解問題出在哪裏?
我的代碼:
import sys
import pandas as pd
import numpy as np
import math
from keras.models import Sequential
from keras.layers import Dense
from keras.layers import LSTM
from sklearn.preprocessing import MinMaxScaler
from sklearn.metrics import mean_squared_error
from sklearn.feature_extraction.text import CountVectorizer
if __name__ == "__main__":
np.random.seed(7)
with open('SMSSpamCollection') as file:
dataset = [[x.split('\t')[0],x.split('\t')[1]] for x in [line.strip() for line in file]]
data = np.array([dat[1] for dat in dataset])
labels = np.array([dat[0] for dat in dataset])
dataVectorizer = CountVectorizer(analyzer = "word",
tokenizer = None,
preprocessor = None,
stop_words = None,
max_features = 5000)
labelVectorizer = CountVectorizer(analyzer = "word",
tokenizer = None,
preprocessor = None,
stop_words = None,
max_features = 5000)
data = dataVectorizer.fit_transform(data).toarray()
labels = labelVectorizer.fit_transform(labels).toarray()
vocab = labelVectorizer.get_feature_names()
print(vocab)
print(data)
print(labels)
data = np.reshape(data, (data.shape[0], 1, data.shape[1]))
input_dim = data.shape
tam = len(data[0])
print(data.shape)
print(tam)
model = Sequential()
model.add(LSTM(tam, input_shape=input_dim))
model.add(Dense(1))
model.compile(loss='mean_squared_error', optimizer='adam')
model.fit(data, labels, epochs=100, batch_size=1, verbose=2)
我嘗試添加SMSSpamCollection
