我正在尝试使用tflearn进行一个非常简单的近似正弦函数,灵感来自this论文。
import tflearn
import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
# generate cosine function
x = np.linspace(-np.pi,np.pi,10000)
y = np.sin(x)
# Network building
net = tflearn.input_data(shape=[10,10000])
net = tflearn.fully_connected(net, 1000)
net = tflearn.layers.core.activation (net, activation='relu')
net = tflearn.regression(net)
# Define model
model = tflearn.DNN(net)
# Start training (apply gradient descent algorithm)
model.fit(x, y,batch_size=10)
但我一直在遇到
ValueError:无法为Tensor u' InputData / X:0'提供形状值(10,),其形状为'(?,10,10000)'
错误。
关于我哪里出错的任何想法?
谢谢!
答案 0 :(得分:0)
更新:我没有为x = np.linspace(-np.pi,np.pi,10000)
张量指定形状:
通过将行更改为np.linspace(-np.pi,np.pi,10000).reshape(-1, 1)
在行input_data(shape=[10,10000])
中,每个输入张量的形状实际上是[None,1],因此将此行更改为net = tflearn.input_data(shape = [None,1])最终解决了问题
