Hi,
If anyone still interested in reading TFRecords, I’ve started a project https://github.com/podgorskiy/DareBlopy 234. It is capable of some basic TFRecords reading and has decent performance (weirdly, seems even faster than TensorFlow, at least in one particular test case)
I used it to train my StyleGAN 13 PyTorch implementation using TFRecords of FFHQ dataset, as well as in some other projects of mine.
Documentation is still an issue, but I’ll be fixing it soon.
