همانطور که میدانید چند وقتیه که گوگل کولب GPUهای Tesla V4 با مشخصات زیر را به صورت رایگان در اختیار محققان قرار داده

16GB of VRAM
160 TFLOPS of GPU power

اما این که چه موقع GPUی K80بهتون بده چه موقع Tesla V4 دست خودتون نیست،
ممکنه به دلایلی مثل استفاده از GPU قوی تر یا مثلا عدم ساپوت K80 از کد شما (مثل دیتابیس Blazing SQL که روی Tesla V4 اجرا میشه ولی روی K80 نه!) میخواهید حتما از تسلا استفاده کنید.
برای اینکار فعلا تنها راهی که من میدونم میشه کرد اینه که کرنلتون را ریست کنید:

Runtime -> Reset all runtimes...

حالا از کجا بفهمیم چه GPUی بهمون داده؟
یه روش ساده که استفاده از دستور

!nvidia-smi

تو نوت بوکه.
روش دیگه اینه که کد زیر را اول نوت بوک یا کد پایتونیتون بزارید که اگر GPU مورد نظرمون را بهمون نداده بود Exception بده!

import pynvml


pynvml.nvmlInit()
handle = pynvml.nvmlDeviceGetHandleByIndex(0)
device_name = pynvml.nvmlDeviceGetName(handle)

if device_name != b'Tesla T4':
  raise Exception("""
    Unfortunately this instance does not have a T4 GPU.
    
    Please make sure you've configured Colab to request a GPU instance type.
    
    Sometimes Colab allocates a Tesla K80 instead of a T4. Resetting the instance.

    If you get a K80 GPU, try Runtime -> Reset all runtimes...
  """)
else:
  print('Woo! You got the right kind of GPU!')

A great course about statistics.
Appropriate for the beginners who have not any prior knowledge about statistics

We live in a complex world with diverse people, firms, and governments whose behaviors aggregate to produce novel, unexpected phenomena. We see political uprisings, market crashes, and a never ending array of social trends. How do we make sense of it? Models. Evidence shows that people who think with models consistently outperform those who don't. And, moreover people who think with lots of models outperform people who use only one. Why do models make us better thinkers? Models help us to better organize information - to make sense of that fire hose or hairball of data (choose your metaphor) available on the Internet. Models improve our abilities to make accurate forecasts. They help us make better decisions and adopt more effective strategies. They even can improve our ability to design institutions and procedures. In this class, I present a starter kit of models: I start with models of tipping points. I move on to cover models explain the wisdom of crowds, models that show why some countries are rich and some are poor, and models that help unpack the strategic decisions of firm and politicians.

The models covered in this class provide a foundation for future social science classes, whether they be in economics, political science, business, or sociology. Mastering this material will give you a huge leg up in advanced courses. They also help you in life. Here's how the course will work. For each model, I present a short, easily digestible overview lecture. Then, I'll dig deeper. I'll go into the technical details of the model. Those technical lectures won't require calculus but be prepared for some algebra. For all the lectures, I'll offer some questions and we'll have quizzes and even a final exam. If you decide to do the deep dive, and take all the quizzes and the exam, you'll receive a Course Certificate. If you just decide to follow along for the introductory lectures to gain some exposure that's fine too. It's all free. And it's all here to help make you a better thinker!

SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python.
