python中的文件位置错误

Question

我试图在我的VQA项目中实现跳过思想向量，但是我在从指定的位置读取文件时遇到了问题。这是一段跳过的代码。

path_to_models = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought'
path_to_tables = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought'

path_to_umodel = path_to_models + 'uni_skip.npz'
path_to_bmodel = path_to_models + 'bi_skip.npz'

def load_model():
    """
    Load the model with saved tables
    """
    # Load model options
    print ('Loading model parameters...')
    with open('%s.pkl'%path_to_umodel, 'rb') as f:
        uoptions = pkl.load(f)
    with open('%s.pkl'%path_to_bmodel, 'rb') as f:
        boptions = pkl.load(f)

这是我调用skipthoughts.py时的错误消息

File "C:/Users/Downloads/Stacked Attention 
Networks/skip_thought/new_skip_thought.py", line 11, in <module>
model = skipthoughts.load_model()

File "skipthoughts.py", line 37, in load_model
with open('%s.pkl'%path_to_umodel, 'rb') as f:

IOError: [Errno 2] No such file or directory: 
'C:/Users/Downloads/Stacked Attention Networks/skip_thoughtuni_skip.npz.pkl'

文件位置不正确。

‘c:/用户/下载/注意力叠加Networks/skip_thoughtuni_skip.npz.pkl’

它应该是

‘c:/用户/下载/注意力叠加Networks/skip_thought/uni_skip.npz.pkl’

Answer 1

程序中唯一的问题是保存在path_to_umodel和path_to_bmodel中的文件路径错误。为了解决这个问题，您可以修改变量path_to_models和path_to_tables，在它们的末尾添加一个/，如下所示：

path_to_models = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought/'

和

path_to_tables = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought/'

或者可以将/添加到uni_skip.npz和bi_skip.npz的开头，然后，这些行变成：

path_to_umodel = path_to_models + '/uni_skip.npz'
path_to_bmodel = path_to_models + '/bi_skip.npz'

更好的是，您可以使用内置到python的os模块中的os函数。只需在程序开始时使用import os，并将其用作：

path_to_umodel = os.path.join(path_to_models, os.sep, 'uni_skip.npz')
path_to_bmodel = os.path.join(path_to_models, os.sep, 'bi_skip.npz')

在这里，os.sep是在运行代码的平台上使用的文件分隔符。对于windows，它是\，对于linux和unix，它是/。最好是使用os.sep，而不是用硬编码代替它。

Answer 2

您需要使用os.path.join，如下所示：

import os

path_to_models = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought'
path_to_tables = 'C:/Users/Downloads/Stacked Attention Networks/skip_thought'

path_to_umodel = os.path.join(path_to_models, 'uni_skip.npz')
path_to_bmodel = os.path.join(path_to_models, 'bi_skip.npz')
