[Solved]: Deep Learning of Darknet on GPU and error “CUDA Error: invalid device ordinal darknet: ./src/cuda.c:36: check_error: Assertion `0′ failed.”
When You after compilation darknet with GPU=1 option You received error during execution darknet command like below:
CUDA Error: invalid device ordinal
darknet: ./src/cuda.c:36: check_error: Assertion `0′ failed.
Abandon (core dumped)
that means that You compiled sources with invalid arch attribute.
For instance existing configuration:
for RTX 2080 TI Dual is incorrect and destination valid arch parameter is:
In makefile You should place arch parameter according valid architecture related to Your GPU specification. Below is listed valid parameters:
