### PyTorch 1.4.0 GPU Configuration and Issues
For configuring PyTorch with GPU support, ensuring the correct installation of CUDA is crucial as it enables PyTorch to leverage NVIDIA GPUs for faster computations[^1]. When using PyTorch version 1.4.0 specifically, compatibility between PyTorch and CUDA versions must be carefully considered.
To verify whether a PyTorch installation supports GPU acceleration:
```python
import torch
print(torch.cuda.is_available())
```
This command checks if CUDA is available within the current environment.
If `torch.cuda.is_available()` returns `False`, several potential issues might exist:
- **CUDA Installation**: Ensure that an appropriate version of CUDA has been installed on the system.
- **Driver Compatibility**: Verify that the graphics driver matches the required version for the installed CUDA toolkit.
- **PyTorch Build**: Confirm that PyTorch was built with CUDA support. Installing via pre-built binaries from official sources usually includes this feature but custom builds may vary.
For troubleshooting specific errors related to GPU configurations in PyTorch 1.4.0, consider checking error messages closely for hints about missing libraries or incompatible software components.
When setting up environments involving multiple packages like OpenCV alongside PyTorch, ensure all dependencies are compatible not only among themselves but also with the operating system's architecture and existing hardware setup.
