Parsing error (Unsupported activation: relu) in ReadDarknetFromCfgStream

edit

thanks for your answer but i already installed opencv 4.1.1 and same error still exist.

indeed, 4.1.1 won't do the trick, since you need this fix

so, 3.4.12 or 4.5.0 will have it

oh i got it now. i using dll libraryand not copile opencv myself to do that change. is there a way to add that relu parameter in my code?

is there a way to add that relu parameter in my code?

no. error comes from the darknet importer, which is part of the opencv dnn module, not from your code

you could try to replace the relu with preluleaky activations in the cfg file, but the quality will probably degrade ;(

thank you very much ... but unfurtunatlly (Unsupported activation: prelu)

sorry, my bad -- leaky not prelu (what all other yolo networks use ...)

i test all other activation function but no one work . Parsing error (Unknown layer type: connected) in ReadDarknetFromCfgStream. i think i have to build opencv myself. thanks
