hi @thyeros, unfortunately we cannot repro this on master and this is not a known KP.  Could you try the debug script in gist:61ac9744858509e175d4ce50258782e4 · GitHub 1 and narrow down which exact part of disable_fake_quant is not working in your environment?  In the debug script, I just copied the disable_fake_quant definition so it’s easy to debug.
