Note

Neuron Driver installed on Deep Learning AMI (DLAMI) with Conda does not support Inf2\Trn1.

If you want to use DLAMI with Conda, please make sure to uninstall aws-neuron-dkms and install aws-neuronx-dkms before using Neuron on DLAMI with Conda.

Note

If you are facing a timeout issue during the model loading process on a Trn1 instance with Ubuntu, that could probably be because of Ubuntu limitations with multiple interfaces. To solve this problem, please follow the steps mentioned here.

Neuron SDK team highly recommends to launch the instances using DLAMIs since they already have a fix for any such problems.
