我要求您将链接发送到具有现成训练神经网络的来源。不管它们是如何分布的，在公共领域或收费，主要是神经网络的名称和关于它的描述，它的作用，它是如何训练的，等等。最好详细一点。还有几张带有工作示例的照片。是的，我用谷歌搜索过，但大多数资源都显示了如何编写自己的网络，我需要现成的网络。谢谢你。

我想以这样一种方式实现脚本，即一个人输入源文件的路径、目标文件的路径、源文件和目标文件，而不干扰代码。该脚本接受值，但在打开文件时，该脚本会引发错误。这是代码

path = [0] * 2
sourcefile = 0
destinationfile = 0

print("Please write your source path:")
input(path[0])
print("Please write your destination path:")
input(path[1])
print("Source name of your file is ")
input(sourcefile)
print("Destination name of your file is ")
input(destinationfile)

with open(r"%s"+"%s" % (path[0], sourcefile), 'r') as file_in:

问题从此刻开始with open。谁知道，请帮忙。

我有一个包含以下内容的文件：

        CREATE TABLE some_name (
fv int,
sv int,
tv int)
CLUSTERED BY (fv,
              sv,
              tv) 
SORTED BY (fv,
           sv,
           tv) INTO 2 BUCKETS;
-- more text afterwards

例如，我需要确保脚本会删除从 Clustered inclusive 到 Buckets inclusive 的所有单词，但不会删除分号。代码如何实现？我被提供了这个：

start_word = "CLUSTERED"
end_word = "BUCKETS"

result_lines = []

with open(target_file, 'r') as f:
    erasing = False
    for line in f:
        if not erasing and start_word in line:
            // begin erasing lines
            erasing = True
            continue

        if erasing and end_word in line:
            // finished erasing lines
            erasing = False
            continue

        if erasing:
            // we are between the start and end of the section we want to erase
            continue
        else:
            // either we haven't started erasing or we have already finished
            result_lines.append(line)

print('\n'.join(result_lines))

但它会删除分号，一般来说，所有与 Clustered 和 Buckets 一致的东西都会被删除。结果应该是这样的：

 CREATE TABLE some_name (
fv int,
sv int,
tv int)
-- more text afterwards;
