Introduction
Deep learning, a subset of machine learning, employs artificial neural networks to glean insights from data, enabling impressive feats like image classification, natural language processing, and speech recognition. Yet, the complexity of training and deploying deep learning models can result in substantial computational demands. This is where GPUs (Graphics Processing Units) come into play, delivering a much-needed performance boost by swiftly executing the myriad operations required. By leveraging CUDA and cuDNN, essential libraries, you can elevate the efficiency of deep learning, especially when working with popular frameworks like PyTorch and TensorFlow.
Unveiling the Power of CUDA and cuDNN
CUDA, an innovation by NVIDIA, serves as a parallel computing platform and programming model. It empowers developers to create code optimized for GPU execution, thereby unlocking the immense computational capacity GPUs offer.
cuDNN complements CUDA as a GPU-accelerated library brimming with specialized functions for deep neural networks. It refines operations such as convolutions, pooling, and activations, translating into heightened performance during both training and inference.
Both CUDA and cuDNN are indispensable when working with PyTorch and TensorFlow on GPUs.
The Essence of Utilizing CUDA and cuDNN
Employing CUDA and cuDNN for deep learning acceleration presents several compelling reasons:
Speed Amplification: The duo significantly accelerates model training and deployment, ensuring faster results.
Access to Limited Resources: CUDA and cuDNN empower you to deploy models on devices with modest computing power, opening doors to more devices.
Simplified Development: With CUDA and cuDNN, you can sidestep intricate GPU programming intricacies, concentrating on the core of deep learning model development.
Installing CUDA and cuDNN: A Navigational Overview
CUDA and cuDNN Installation Steps for Windows / Linux / MacOS
Visit the NVIDIA CUDA Toolkit webpage and select the Windows / Linux / MacOS based on the OS and version suitable for your system.
NOTE: Install only the 11.7 or 11.8 for PyTorch installation as we have the stable versions of torch with GPU only in this two versions. The given link is for 12.2, to download 11.x use below link:
https://developer.nvidia.com/cuda-11-7-0-download-archive – 11.7
https://developer.nvidia.com/cuda-11-8-0-download-archive – 11.8
Adhere to the installation instructions provided on the webpage. Download cuDNN from the NVIDIA cuDNN webpage and install it according to the provided instructions.
After downloading cuDNN, extract the files if it is in zip (Windows) file, tar (Linux) file or directly install if you downloaded the files in deb or rpm format for Linux.
Refer the document below for Linux installation and MacOS:
Installing cuDNN for Linux and MacOS : https://docs.nvidia.com/deeplearning/cudnn/archives/cudnn_765/pdf/cuDNN-Installation-Guide.pdf
After extracting the zip or tar files, copy the files from the respective folders in cuDNN to the appropriate folders in CUDA, to find the path of CUDA open CMD as an administrator and run the command: “where nvcc”
copy only till the . . .\CUDA\v11.x
Validating CUDA Installation
After installation, verify their presence with the following commands: “nvcc –version # Check CUDA version”
Installing torch / TensorFlow with CUDA
First ensure to uninstall normal torch without GPU if you need torch to install with the command: “pip uninstall torch” you will be prompted to confirm the uninstallation give ‘Y’ and proceed.
If you already don’t have, you will get a message like below:
Similar for the tensorflow also. . .
Now to install torch with GPU, visit the PyTorch with CUDA page and select the environment you are using like conda, pip and so on alongwith CUDA version and copy paste the code in the terminal.
My code and output: ( CUDA Version – 11.7 and both CUDA and cuDNN installed and the files are moved successfully ) “pip3 install torch torchvision torchaudio –index-url https://download.pytorch.org/whl/cu117”
Now to install TensorFlow with GPU, visit the TensorFlow with CUDA page and select the environment you are using like conda, pip and so on and also the Operating System you are using along with CUDA version and copy paste the code in the terminal.
Empowering PyTorch and TensorFlow with CUDA and cuDNN
PyTorch:
import torch
device = torch.device(“cuda” if torch.cuda.is_available() else “cpu”)
model.to(device)
data = data.to(device)
TensorFlow:
import tensorflow as tf
device = tf.device(“gpu” if tf.test.is_gpu_available() else “cpu”)
with device:
# Define and perform operations
…
Conclusion
CUDA and cuDNN emerge as formidable allies for fortifying deep learning endeavours, harnessing the potential of GPUs to the fullest. By assimilating the instructions outlined herein, you can seamlessly integrate CUDA and cuDNN, thereby turbocharging your deep learning undertakings.
