WebApr 14, 2024 · Implementing Gradient Check in practice. While implementing Gradient Check across a lot of projects I have observed that the value of ϵ = 10⁻⁶ or 10⁻⁷ does the work most of the time. So, with the above-mentioned similarity formula and this value of ϵ, you find that formula yields a value smaller than 10⁻⁷ or 10⁻⁸, which is ... WebNov 20, 2016 · 10. You can check whether your gradients have NaN by tf.check_numerics: grad_check = tf.check_numerics (clipped_gradients) with tf.control_dependencies ( [grad_check]): self.optimizer = opt.apply_gradients (zip (clipped_gradients, params)) The grad_check would throw InvalidArgument if clipped_gradients is NaN or infinity.

WebWhen performing gradient check, remember to turn off any non-deterministic effects in the network, such as dropout, random data augmentations, etc. Otherwise these can clearly introduce huge errors when estimating the numerical gradient. The downside of turning off these effects is that you wouldn’t be gradient checking them (e.g. it might be ...
