我對Tensorflow和tflearn很新穎 到目前爲止,我已經研究了幾個教程,並一直試圖將tflearn泰坦尼克號應用於動物園動物數據集(http://archive.ics.uci.edu/ml/datasets/Zoo)。培訓工作很好,但是當我嘗試對我輸入的數據嘗試使用model.predict時,出現以下錯誤Tflearn model.predict無法提供形狀的值(1,1,17)
無法提供張量'InputData/X:0'的形狀值(1,1,17) ,它具有形狀 '(?16)'
這裏的Python代碼
from __future__ import print_function
import numpy as np
import tflearn
# Load CSV file, indicate that the first column represents labels
from tflearn.data_utils import load_csv
data, labels = load_csv('zoo.csv', target_column=-1,
categorical_labels=True, n_classes=8)
# Preprocessing function
def preprocess(data, columns_to_ignore):
# Sort by descending id and delete columns
for id in sorted(columns_to_ignore, reverse=True):
[r.pop(id) for r in data]
return np.array(data, dtype=np.float32)
# Ignore 'name' and 'ticket' columns (id 1 & 6 of data array)
to_ignore=[0]
# Preprocess data
data = preprocess(data, to_ignore)
# Build neural network
net = tflearn.input_data(shape=[None,16])
net = tflearn.fully_connected(net, 128)
net = tflearn.dropout(net, 1)
net = tflearn.fully_connected(net, 128)
net = tflearn.dropout(net, 1)
net = tflearn.fully_connected(net, 8, activation='softmax')
net = tflearn.regression(net)
# Define model
model = tflearn.DNN(net)
# Start training (apply gradient descent algorithm)
model.fit(data, labels, n_epoch=1, validation_set=0.1, shuffle=True, batch_size=17, show_metric=True)
ant = ['ant', 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 1, 0, 8, 0, 0, 0]
# Preprocess data
ant = preprocess([ant], to_ignore)
# Predict surviving chances (class 1 results)
pred = model.predict([ant])
print("Ant is:", pred[0])
我使用重塑試過了,沒有相當的工作。我發現使用搜索的類似問題在訓練階段出現此錯誤,而不是預測。
請分享一下''data'&'''vars以及'zoo.csv'的樣本(沒有樣本數據,任何人都可以幫忙......) – desertnaut
