numpy zeros 错误 - TypeError：np.zeros 无法理解数据类型

Question

   dir_path='/home/jeevitha/8_8_192_features'
    #count = 1
    for name in os.listdir(dir_path):
    #count += 1
    video_id = name.split('.')[0]
    fname='/home/jeevitha/8_8_192_features'+video_id+'.pkl'
    if not (os.path.isfile(fname) ):
        video_file_path=os.path.join(dir_path, name)
        features=open(video_file_path, 'rb')  
        features=list() 
        new_features = np.zeros(8,8,192)
        for i in features:
            new_features+=features[i]
        new_features=new_features/len(features)
        dump(features,open(fname,'wb'))  

请帮助我，使用 np.zeros 存储泡菜文件

我试过了 导入数学和numpy 仍然显示“数据类型不理解”之类的错误

Answer 1

如果有多个维度，您必须提供一个元组， 见here

np.zeros((8,8,192)) 是你想要的，或者 np.zeros([8,8,192]) 就像 filthysocks 所说的

Answer 2

它已排序，

 dir_path='/home/jeevitha/8_8_192_features'
    #count = 1
    for name in os.listdir(dir_path):
    #count += 1
    video_id = name.split('.')[0]
    fname='/home/jeevitha/8_8_192_features'+video_id+'.pkl'
    if not (os.path.isfile(fname) ):
        video_file_path=os.path.join(dir_path, name)
        features=open(video_file_path, 'rb')  
        features=list() 
        new_features = np.zeros([8,8,192])
        for i in features:
            new_features+=features[i]
        new_features=new_features/len(features)
        dump(new_features,open(fname,'wb'))

Answer 3

应该是

new_features = np.zeros([8,8,192])

编辑： 这个 sn-p 还有更多问题。

features=open(video_file_path, 'rb')  
features=list() #remove this. debug code?
new_features = np.zeros(8,8,192)
for i in features:
    new_features+=features[i]
new_features=new_features/len(features)
dump(features,open(fname,'wb')) 

features 设置为空列表并保存。 此外，我猜你想保存 new_features？
