I’ve purchased recently a GTX 1660 and decided to install the CUDA Toolkits to have some fun with a chess engine called “CrazyAra” however,
Since I have CUDA Toolkit 11.1 installed, whenever I try to run it it says the following:
“[12/31/2020-00:42:02] [E] [TRT] INVALID_CONFIG: The engine plan file is generated on an incompatible device, expecting compute 7.5 got compute 6.1, please rebuild.”
After a quick search on wiki I found out that my GPU has the Turing(7.5) architecture and the current file is built to run on Pascal(6.1).
Is there any sort of emulation to “downgrade” it from 7.5 to 6.1 in order to run it? Or is it obligatory to actually compile the whole network on 7.5?
Sorry about the confusion,
