The Intel x86 and AMD64 / x86-64 series of processors use the little-endian format whereas s390x architecture uses big-endian format. Current MXNet parameter serialization format is just a memory dump and can't be loaded on a system with different endianness. For MXNet 2, we're switching to using the numpy serialization format which will prevent such issues (https://numpy.org/devdocs/reference/generated/numpy.lib.format.html) For now, you can't use the pretrained models directly on s390x architecture but you'd need some workaround where you load the parameter on a x86 machine, call `asnumpy`, save via numpy and finally load the parameters on s390x machine using numpy and convert them to mxnet. Would that work for you? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
