My original thinking was that companies needing to use transformers, LSTMs, etc., would want to fund the development after doing the simple work to evaluate NN-512's ResNeXt or DenseNet performance on their hardware
Same with development of tooling (network conversion, parameter import). It just takes a lot of time/effort for me to write the code. It's easy to say that support for AVX, AVX2, etc., would be nice, but that's months of hard work (unfunded)
I guess we agree that a niche tool like NN-512, that has a reduced feature set (trimmed to allow one person to complete it and release it for free), has trouble competing with the huge, free, flexible, multi-target tools funded by large companies
In retrospect this is obvious!
