Question

我在我的数据测试中编写了一个代码，但是在形状上有错误。我的矩阵“X”包含4列和3824行。我想用4输入和1输出来预测某个地方的辐射剂量将来我会增加条目，但我想先用这个数据库进行测试

使用示例：https://github.com/tflearn/tflearn/blob/master/examples/images/dnn.py

代码：

from __future__ import division, print_function, absolute_import

import tflearn
from sklearn import preprocessing
import Planilha as pl

X, Y = pl.dados('TR')
testX, testY = pl.dados('t')

scaler = preprocessing.StandardScaler()
X = scaler.fit_transform(X)
testX = scaler.fit_transform(testX)

m = X.shape[0]
n = X.shape[1]
print(X.shape)
print(Y.shape)

# Building deep neural network
input_layer = tflearn.input_data(shape=[None, 4]) 
dense1 = tflearn.fully_connected(input_layer, 1, activation='tanh',
                             regularizer='L2', weight_decay=0.001)
dropout1 = tflearn.dropout(dense1, 0.8)
dense2 = tflearn.fully_connected(dropout1, 1, activation='tanh',
                             regularizer='L2', weight_decay=0.001)
dropout2 = tflearn.dropout(dense2, 0.8)
softmax = tflearn.fully_connected(dropout2, 10, activation='softmax')

# Regression using SGD with learning rate decay and Top-3 accuracy
sgd = tflearn.SGD(learning_rate=0.1, lr_decay=0.96, decay_step=1000)
top_k = tflearn.metrics.Top_k(3)
net = tflearn.regression(softmax, optimizer=sgd, metric=top_k,
                     loss='categorical_crossentropy')

# Training
model = tflearn.DNN(net, tensorboard_verbose=0)
model.fit(X, Y, n_epoch=20, validation_set=(testX, testY),
      show_metric=True, run_id="dense_model")

消息错误：

 ValueError: Cannot feed value of shape (64, 4) for Tensor 'InputData/X:0', which has shape '(?, 3824, 4)'

请帮帮忙？
