How to choose the PyTorch version on CentOS
Apr 14, 2025 pm 06:51 PMInstalling PyTorch on CentOS system requires careful selection of the appropriate version and consider the following key factors:
1. System environment compatibility:
Operating system: CentOS 7 or higher is recommended.
CUDA and cuDNN: The PyTorch version is closely related to the CUDA version. For example, PyTorch 1.9.0 requires CUDA 11.1, while PyTorch 2.0.1 requires CUDA 11.3. The cuDNN version must also match the CUDA version. Before selecting the PyTorch version, be sure to confirm that compatible CUDA and cuDNN versions have been installed.
Python version: PyTorch officially supports Python versions 3.6 to 3.9, but the compatibility of different PyTorch versions for Python versions is slightly different. Python 3.7 or 3.8 is recommended for best compatibility and performance.
GPU acceleration: If you need to use NVIDIA GPU acceleration computing, you must install the PyTorch version that supports CUDA and ensure that the GPU driver and CUDA version are correctly installed and compatible.
2. Installation steps:
-
Create a virtual environment (recommended): Use conda to create a separate virtual environment to avoid conflicts with other Python environments in the system.
conda create -n pytorch_env python=3.8 # It is recommended to use Python 3.8 conda activate pytorch_env
-
Install PyTorch:
-
CPU version: If GPU acceleration is not required, install the CPU version of PyTorch:
pip install torch torchvision torchaudio
-
GPU version: If GPU acceleration is required, select the corresponding installation command according to your CUDA version. For example, CUDA version 11.3:
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu113
Please replace
cu113
with the CUDA version number you actually installed.
-
-
Verify the installation: After the installation is complete, run the following code to verify that PyTorch is installed successfully and that the GPU is available:
import torch print(torch.__version__) print(torch.cuda.is_available()) # True Indicates that the GPU is available
3. Things to note:
- Driver: Before installing PyTorch, make sure that the NVIDIA graphics card driver is installed that is compatible with the CUDA version.
- System resources: Different PyTorch versions have different requirements for system resources (memory, etc.). Please check whether the system resources are sufficient before installation.
After completing the above steps, you can successfully use PyTorch for deep learning development on the CentOS system. Remember, choosing the correct CUDA version is the key to successful installation of the GPU version PyTorch.

Ethereum is a decentralized application platform based on smart contracts, and its native token ETH can be obtained in a variety of ways. 1. Register an account through centralized platforms such as Binance and Ouyiok, complete KYC certification and purchase ETH with stablecoins; 2. Connect to digital storage through decentralized platforms, and directly exchange ETH with stablecoins or other tokens; 3. Participate in network pledge, and you can choose independent pledge (requires 32 ETH), liquid pledge services or one-click pledge on the centralized platform to obtain rewards; 4. Earn ETH by providing services to Web3 projects, completing tasks or obtaining airdrops. It is recommended that beginners start from mainstream centralized platforms, gradually transition to decentralized methods, and always attach importance to asset security and independent research, to

To avoid taking over at high prices of currency speculation, it is necessary to establish a three-in-one defense system of market awareness, risk identification and defense strategy: 1. Identify signals such as social media surge at the end of the bull market, plunge after the surge in the new currency, and giant whale reduction. In the early stage of the bear market, use the position pyramid rules and dynamic stop loss; 2. Build a triple filter for information grading (strategy/tactics/noise), technical verification (moving moving averages and RSI, deep data), emotional isolation (three consecutive losses and stops, and pulling the network cable); 3. Create three-layer defense of rules (big whale tracking, policy-sensitive positions), tool layer (on-chain data monitoring, hedging tools), and system layer (barbell strategy, USDT reserves); 4. Beware of celebrity effects (such as LIBRA coins), policy changes, liquidity crisis and other scenarios, and pass contract verification and position verification and

Introduction to Statistical Arbitrage Statistical Arbitrage is a trading method that captures price mismatch in the financial market based on mathematical models. Its core philosophy stems from mean regression, that is, asset prices may deviate from long-term trends in the short term, but will eventually return to their historical average. Traders use statistical methods to analyze the correlation between assets and look for portfolios that usually change synchronously. When the price relationship of these assets is abnormally deviated, arbitrage opportunities arise. In the cryptocurrency market, statistical arbitrage is particularly prevalent, mainly due to the inefficiency and drastic fluctuations of the market itself. Unlike traditional financial markets, cryptocurrencies operate around the clock and their prices are highly susceptible to breaking news, social media sentiment and technology upgrades. This constant price fluctuation frequently creates pricing bias and provides arbitrageurs with

The core methods of secure access to Binance official website are: 1. Manually enter the official website and add bookmarks; 2. Verify the lock icon and HTTPS in the browser address bar; 3. Avoid clicking on links in search engines, social media or unknown messages. When downloading a new version of the application, the desktop should be downloaded from the official website, iOS users should go through the App Store, and Android users should choose Google Play. If you cannot access it, you must download it through the verified official website. Always enable two-factor verification and be alert to false customer service information to ensure your account is secure.
