Keras資料集匯入問題

keras 中文文件

from keras.datasets import fashion_mnist

(x_train, y_train), (x_test, y_test) = fashion_mnist.load_data()

import matplotlib.pyplot as plt

import numpy as np

with gzip.open(path[0], 'rb') as lbpath:

with gzip.open(path[1], 'rb') as imgpath:

(train_images, train_labels), (test_images, test_labels) = load_data(path, files)
# 測試
執行結果 
出現：using tensorflow backend.不需要理會
上述兩種方法可對其他資料集同理操作

ubuntu 絕對路徑：例如在目錄/home/local/temp下有乙個檔案filename.txt那麼filename.txt檔案的絕對路徑就是/home/local/tempubuntu 相對路徑：如果你當前路徑是在/home/temp下,那麼filename.txt檔案的相對路徑就是 ./temp注：ubuntu 中根目錄" / "；當前目錄" ./ "；當前目錄的上一級目錄(如果有上一級目錄的話)" ../ "；

參考：常用資料集datasets-keras資料的匯入

ubuntu相對路徑和絕對路徑
