Disclaimer: am a co-founder of this company Applied Brain Research has software called Nengo (www.nengo.ai) explicitly for developing neural network models and compiling them to different backends, including CPUs, GPUs, and neuromorphic hardware (Intel's Loihi, Spinnaker, Spinnaker 2, BrainDrop). It's been battle tested for over 10 years of developing models, built the world's largest functional brain model (https://bit.ly/2VNGgSX https://bit.ly/2VNGgSX), integrates deep learning and spiking neural networks. Would be interested to hear your thoughts on it.
