Hi @matteosal, the implementations of executor are totally different between v1.6 and v2.0. In v1.6, we are using executor C-APIs exposed from backend ([example](https://github.com/apache/incubator-mxnet/blob/c76593162c2a5e421243dd09a8c3cde044efaa3f/python/mxnet/executor.py#L150)), but in v2.0, we are using CachedOp APIs ([example](https://github.com/apache/incubator-mxnet/blob/5f0efbbe33a1ef2af140e91a8fd367cd3bf92373/python/mxnet/executor.py#L183)). You could try to add some parameters when initializing [CachedOp](https://github.com/apache/incubator-mxnet/blob/5f0efbbe33a1ef2af140e91a8fd367cd3bf92373/python/mxnet/executor.py#L124) to do hybridization (reference: [ref1](https://github.com/apache/incubator-mxnet/blob/5f0efbbe33a1ef2af140e91a8fd367cd3bf92373/python/mxnet/gluon/block.py#L1391-L1406), [ref2](https://github.com/apache/incubator-mxnet/pull/20462/files#diff-0b3b9d55159f8526d638cd6f3d571c1eeed96f3bcdc37492425a0749d5a3f208L124)) to see the memory allocation optimizations. Also, you can change [MXNET_GPU_MEM_POOL_TYPE](https://mxnet.apache.org/versions/master/api/faq/env_var) environment variable to try different memory pool types. -- This is an automated message from the Apache Git Service.
