您好，我正在尝试制作预测 CNN 的股票，因为我想挑战自己，但我遇到了这个错误。它认为 Convd2D 没有完全定义，但我不知道还有什么可以解决这个错误。有人可以帮我吗这是我的代码

import tflearn
import numpy as np
from tflearn.layers.conv import conv_2d, max_pool_2d
from tflearn.layers.core import input_data, dropout, fully_connected
from tflearn.layers.estimator import regression
import csv
import math

prices = []
templist = []
X = []
Y = []
i=0

def get_data(filename):
    with open(filename, 'r') as csvfile:
        csvFileReader = csv.reader(csvfile)
        next(csvFileReader)
        for row in csvFileReader:
            prices.append(float(row[1]))
    return

get_data('intc.csv')
i=len(prices)-5
while i>5:
    X.append(prices[i-5:i])
    Y.append(prices[i-6])
    i-=1



#X, Y, test_x, test_y = mnist.load_data(one_hot=True)

X = np.reshape(X,(-1,len(X),len(X[0]),1))

convnet = input_data(shape=[None, 241, 5, None], name='input')

convnet = conv_2d(convnet, 32, 1, activation='relu')
convnet = max_pool_2d(convnet, 1)

convnet = conv_2d(convnet, 64, 1, activation='relu')
convnet = max_pool_2d(convnet, 1)

convnet = fully_connected(convnet, 1024, activation='relu')
convnet = dropout(convnet, 0.8)

convnet = fully_connected(convnet, 1, activation='softmax')
convnet = regression(convnet, optimizer='adam', learning_rate=0.01, loss='categorical_crossentropy', name='targets')

model = tflearn.DNN(convnet)
model.fit({'input': X}, {'targets': Y}, n_epoch=2, snapshot_step=500, show_metric=True)
model.save('quicktest.model')

我得到的错误是

    convnet = conv_2d(convnet, 32, 1, activation='relu')

    "but instead was %s." % (name, shape))
ValueError: Shape of a new variable (Conv2D/W) must be fully defined, but instead was (1, 1, ?, 32).

谁能帮忙谢谢。

【解决方案1】：

这里的错误与input_data 函数有关。您应该完全定义输入数据形状。您可以将None 用于批量维度，但不能用于任何其他输入维度。

# replace this line
convnet = input_data(shape=[None, 241, 5, None], name='input')
# hopefully with your correct input dimension. you need provide a value
# in your case
num_channels =1
convnet = input_data(shape=[None, 241, 5, num_channels], name='input')
