我正在Rust中构建自己的Tensor类,我试图让它像PyTorch的实现一样.

以编程方式存储张量的最有效方法是什么,但具体来说,是像Rust这样的强类型语言？ 是否有任何资源可以提供有关如何完成此操作的深入见解？

我目前正在构建一个连续的数组,因此,给定尺寸3 x 3 x 3,我的数组中只有3^3元素,这将代表张量.然而,这确实使得数组的一些数学运算和操作更加困难.

张量的维度应该是动态的,这样我就可以得到一个n尺寸张量.

在文档中，它说该函数已存在， winapi::um::wincrypt::CryptDecrypt但是当我安装 crate 并将其引入我的项目时，一切正常，直到我尝试调用该函数，并收到以下错误消息：

error[E0433]: failed to resolve. Could not find `wincrypt` in `um`
  --> src\main.rs:68:39
   |
68 |  let decrypted_password = winapi::um::wincrypt::CryptDecrypt(password);
   |                                       ^^^^^^^^ Could not find `wincrypt` in `um`

我的目标是从 Chrome 存储密码的计算机上的“本地数据”文件中解密密码。我正在使用Rust 中win32crypt调用的 Windows API 绑定winapi。我正在尝试chromepass在 Rust 中完成与但类似的事情。

我正在使用python来创建一个简单的信息检索程序,它获取clientID和用户的客户端ID是txt文件看起来像每行的前5个字符

我希望用户输入一个5个字母的ID,并在我提出这个时刻检查每个行中的一个特定客户ID:

clientID = input('Enter your clientID : ')

fob = open('clientRecords.txt', 'r') # opens file stores it in a var called fob and reads from it
if (clientID in fob.readline(5)):
    print('Access granted')
else:
    print('Access denied')
fob.close()

但这只检查第一行的前5个字母而不是全部.

这就是文本文件的实际外观:
