Training a feed forward network on GPU using Chainer. After training some batches, getting aerror "CUDARuntimeError: cudaErrorIllegalAddress: an illegal memory access was encountered".

only 1.5GB out of 11GB gpu memory is in use. Once the error is encountered, attempt to create a small cupy array too fails with same error.

Chainer : v6.5.0 Cupy : v6.5.0

Supply your code and specifically point to the line where the error is generated. – iliar Dec 01 '19 at 14:37
When supplying the code make sure you supply a minimal reproducible example (reduce it to the simplest example that still generates the same error). – iliar Dec 01 '19 at 14:39
Hi @Jose, were you using SSD model in Chainer? – TulakHord Aug 19 '20 at 06:22
