NVCV_ERR_RESOLUTION: The specified image resolution is not supported.
NVCV_ERR_UNSUPPORTEDGPU: The GPU is not supported.
NVCV_ERR_WRONGGPU: The current GPU is not the one selected.
NVCV_ERR_UNSUPPORTEDDRIVER: The currently installed graphics driver is not supported.
NVCV_ERR_MODELDEPENDENCIES: There is no model with dependencies that match this system.
NVCV_ERR_PARSE: There has been a parsing or syntax error while reading a file.
NVCV_ERR_MODELSUBSTITUTION: The specified model does not exist and has been substituted.
NVCV_ERR_READ: An error occurred while reading a file.
NVCV_ERR_WRITE: An error occurred while writing a file.
NVCV_ERR_PARAMREADONLY: The selected parameter is read-only.

NVCV_ERR_TRT_BINDINGS: Unexpected TensorRT bindings.
NVCV_ERR_TRT_CONTEXT: An error occurred while creating a TensorRT context.
NVCV_ERR_TRT_INFER: There was a problem creating the inference engine.
NVCV_ERR_TRT_ENGINE: There was a problem deserializing the inference runtime engine.
NVCV_ERR_NPP: An error has occurred in the NPP library.
NVCV_ERR_CONFIG: No suitable model exists for the specified parameter configuration.
NVCV_ERR_TOOSMALL: The supplied parameter or buffer is not large enough.
NVCV_ERR_TOOBIG: The supplied parameter is too big.
NVCV_ERR_WRONGSIZE: The supplied parameter is not the expected size.
NVCV_ERR_OBJECTNOTFOUND: The specified object was not found.
NVCV_ERR_SINGULAR: A mathematical singularity has been encountered.
NVCV_ERR_NOTHINGRENDERED: Nothing was rendered in the specified region.
NVCV_ERR_OPENGL: An OpenGL error has occurred.
NVCV_ERR_DIRECT3D: A Direct3D error has occurred.
NVCV_ERR_CUDA_MEMORY: The requested operation requires more CUDA memory than is available.
NVCV_ERR_CUDA_VALUE: A CUDA parameter is not within its acceptable range.
NVCV_ERR_CUDA_PITCH: A CUDA pitch is not within its acceptable range.
NVCV_ERR_CUDA_INIT: The CUDA driver and runtime could not be initialized.
NVCV_ERR_CUDA_LAUNCH: The CUDA kernel failed to launch.
NVCV_ERR_CUDA_KERNEL: No suitable kernel image is available for the device.
NVCV_ERR_CUDA_DRIVER: The installed NVIDIA CUDA driver is older than the CUDA runtime library.
NVCV_ERR_CUDA_UNSUPPORTED: The CUDA operation is not supported on the current system or device.
NVCV_ERR_CUDA_ILLEGAL_ADDRESS: CUDA attempted to load or store an invalid memory address.
NVCV_ERR_CUDA: An unspecified CUDA error has occurred.

Note

Many other CUDA-related errors exist that are not listed here. However, you can use the function NvCV_GetErrorStringFromCode() to convert the error code into a string to help you debug.
