Python TFLearn Shape of a new variable (Conv2D/W) must be fully defined, but instead was (1, 1, ?, 32)

Question

Hi am am trying to make a stock predicting CNN because I wanted to challenge my self and I cam across this error It thinks that Convd2D is not fully defined but I don't know what else to put there to fix that error. can someone help me here is my code

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')

The error that I get is

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

Can someone help please Thanks.

Here the errors is related to the input_data function. You should fully define input data shape. you can use None for batch dimension, but not for any other input dimensions.

# 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')
