### CUDNN Version 7.4 Installation and Compatibility
CUDNN (CUDA Deep Neural Network library) is a GPU-accelerated deep learning library developed by NVIDIA to enhance performance of neural network applications on CUDA-enabled GPUs. When installing CUDNN version 7.4, it's important to ensure that all dependencies are correctly configured.
#### System Requirements
To successfully install CUDNN 7.4, the system must meet specific requirements regarding operating systems and CUDA versions:
- **Operating Systems**: Oracle Linux 7.4 supports various kernel packages as part of its update release[^2]. Similarly, Ubuntu 16.04 has been widely used alongside CUDA installations for machine learning frameworks such as TensorFlow or PyTorch.
- **CUDA Versions**: For optimal compatibility, CUDNN 7.4 works best with CUDA 9.0 or later versions. In some configurations involving newer hardware like GTX 1080 Ti under Ubuntu 16.04, users have reported successful setups using both CUDA 10.0 combined with either CUDNN 7.4.2 or 7.6.4[^5].
#### Steps for Installing CUDNN 7.4
The process involves downloading appropriate binaries from NVIDIA’s official site based upon your architecture type—whether you're working within an environment utilizing `libcudnn.so.5` versus `.so.7`. Ensure these match exactly what was downloaded earlier before proceeding further into linking steps outlined below.
```bash
sudo cp cuda/include/cudnn*.h /usr/local/cuda/include/
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*
```
Additionally, modify `/etc/profile`, adding paths necessary so they can be recognized during compilation phases without manual intervention each time invoking commands related thereto via shell scripting methods shown hereafter :
```bash
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=<cudnn-install-path>:$LD_LIBRARY_PATH
source ~/.bashrc
```
This ensures proper linkage between installed libraries including those provided through Anaconda distributions where potential conflicts may arise due HDF5 discrepancies which could otherwise impede functionality unless addressed accordingly per instructions given previously concerning downgrading said component specifically targeting Python environments managed thusly ^[3]^ .
Finally verify everything functions properly executing command line utility designed explicitly towards monitoring status information pertinent graphical processing units present inside host machines running Linux-based kernels mentioned throughout this document while ensuring drivers themselves were indeed set up according manufacturer guidelines stipulated elsewhere hereinabove too^ [5]^ .
