How to solve PyTorch compatibility issues on CentOS

linux python centos tool ai pycharm pip installation

Installing and configuring PyTorch on a CentOS system to make full use of GPU-accelerating deep learning tasks can follow these steps:

Step 1: Install Anaconda3

First, use Anaconda3 as a Python environment management tool to facilitate the installation and management of PyTorch and its dependent libraries. Download the Anaconda3 installation script and execute:

 wget https://repo.anaconda.com/archive/Anaconda3-2024.05-Linux-x86_64.sh
bash Anaconda3-2024.05-Linux-x86_64.sh

Step 2: Create a virtual environment

To avoid conflicts with the existing Python environment of the system, it is recommended to create a separate virtual environment:

 conda create -n pytorch python=3.10
conda activated pytorch

Step 3: Install PyTorch

Select the appropriate PyTorch installation command based on your CUDA version. Please visit the PyTorch official website to obtain the latest installation instructions that match your system configuration (CUDA version, CPU/GPU). The following two common methods are provided:

  • Use conda to install (recommended): Replace cudatoolkit=12.1 for your actual CUDA version number.
 conda install pytorch torchvision torchaudio cudatoolkit=12.1 -c pytorch
  • Install using pip: Replace cu121 with the identifier corresponding to your CUDA version number (for example, cpu represents the CPU version).
 pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

Step 4: Verify the installation

Run the following Python code to check if PyTorch is installed successfully and has access to the GPU:

 import torch
print(torch.__version__)
print(torch.cuda.is_available())

torch.cuda.is_available() returns True to indicate that PyTorch is correctly installed and can use the GPU.

Step 5: Troubleshooting

  • Version incompatible: If NumPy and PyTorch version conflict occur, try to downgrade NumPy:
 pip install numpy==1.23.5 # Replace with the appropriate NumPy version
  • Conda environment not found: If the IDE (such as PyCharm) cannot recognize the conda environment, please manually configure the Python interpreter path to point to the Python executable file in your pytorch virtual environment.

Important tips:

  • Driver: Make sure that NVIDIA graphics card drivers are installed that are compatible with your CUDA version.
  • GPU support: If your CentOS system supports GPU, it is highly recommended to install the GPU version of PyTorch to significantly improve computing speed.
  • Resource: Before installation, please check whether the system resources (memory, etc.) meet the requirements of PyTorch.

When encountering problems, please refer to the official PyTorch documentation or seek community support. After successfully completing the above steps, you can use PyTorch to perform deep learning development on CentOS system.

Bitcoin (BTC) is a digital asset created and run based on cryptography principles. It does not rely on specific central institutions, such as banks or governments, to issue and manage. Its concept was first proposed in 2008 by an individual or group named "Satoshi Nakamoto" in a paper titled "Bitcoin: A peer-to-peer electronic cash system."

Table of Contents Markets are in a “relative equilibrium state” for the rest of 2025 Bitcoin Outlook is positive Although Bitcoin prices have fallen from all-time highs, Glassnode points out that the current market has entered a “relative equilibrium position”. According to analysis by on-chain data platform Glassnode, as Bitcoin price gradually rebounds after a local low of $112,000, the selling pressure of short-term holders (STH) in profitable state is weakening. In a market report released on Wednesday, Glassnode said that short-term holders (referring to investors who have held the currency for less than 155 days) have significantly "cooled". Data shows that the "spending output profit margin" (SOPR) measuring the selling ratio of recent buy and profitable investors has declined

The price in 2025 is driven by market cycles and celebrity effects, especially depending on whether Elon Musk-related companies use DOGE payments; 2. It may experience a bull market correction from 2026 to 2027, and the price will decline significantly; 3. By 2030, if DOGE can expand a wide range of application scenarios and improve technical performance, the long-term price may be stable at $1.00 or even higher; 4. If it cannot be transformed into a practical asset and only rely on the community and celebrity effects, its attractiveness may weaken, and the price will stagnate for a long time or be emerging.
