一、可爱的聊天机器人 当你开始构建聊天机器人时,了解聊天机器人做什么和它们看起来像什么是非常重要的。 你一定听说过 Siri,IBM Watson,Google Allo 等。这些机器人试图解决的基本问题是成为一个中介,帮助用户变得更有生产力。它们通过允许用户更少地担心如何检索信息以及获取特定数据可能需要的输入格式来做到这一点。
The data that we will be focusing on is going to be the NMME seasonal climate prediction, which is a global dataset of 1 degree (~ 100km) spatial resolution and monthly temporal resolution with multiple months ahead forecast lead time. To make the analysis simpler, we will only focus on ...

Gradio offers a low-level approach for designing web apps with more customizable layouts and data flows with thegr.Blocksclass. Blocks supports things like controlling where components appear on the page, handling multiple data flows and more complex interactions (e.g. outputs can serve as inputs...
We can use the same function to generate multiple realizations or an array of random numbers from the same distribution. 我们可以使用同一个函数从同一个分布生成多个实现或一个随机数数组。 If I wanted to generate a 1d array of numbers,I will simply insert the size of that array, say 5 in ...
To add multiple Exceptions to the except clause, you need to pass them as parenthesized tuple as the first argument. The second argument is an optional name, which when supplied will bind the Exception instance that has been raised. Example, some_list = [1, 2, 3] try: # This should ...

Optionally, try to compile a dynamic Bash extension to speed up Pyenv. Don't worry if it fails; Pyenv will still work normally: cd ~/.pyenv && src/configure && make -C src MacOS The options from theLinux section abovealso work but Homebrew is recommended for basic usage. ...
Furthermore, the inner functions aren’t defined until the parent function is called. They’re locally scoped to parent(), meaning they only exist inside the parent() function as local variables. Try calling first_child(). You’ll get an error:...
