From 314c7eee43521cea02deb3e91f170c64b37b7578 Mon Sep 17 00:00:00 2001 From: hrehard Date: Fri, 17 Jul 2026 14:51:31 -0700 Subject: [PATCH] fix(examples): use valid instance_count for Nova serverful SMTJ SFT SFTTrainer for amazon.nova-2-lite-v1 serverful SMTJ fine-tuning requires instance_count in {4, 8, 16, 32}; the notebook used instance_count=2, which the SDK rejects client-side at train() with "Node/Instance count '2' is not supported. Allowed values: [4, 8, 16, 32]". Set both SFTTrainer compute blocks to 4 (the minimum valid value). --- .../sft_finetuning_serverful_smtj.ipynb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/v3-examples/model-customization-examples/sft_finetuning_serverful_smtj.ipynb b/v3-examples/model-customization-examples/sft_finetuning_serverful_smtj.ipynb index f130931e54..fec96aaea9 100644 --- a/v3-examples/model-customization-examples/sft_finetuning_serverful_smtj.ipynb +++ b/v3-examples/model-customization-examples/sft_finetuning_serverful_smtj.ipynb @@ -88,7 +88,7 @@ " s3_output_path=S3_OUTPUT_PATH,\n", " compute=TrainingJobCompute(\n", " instance_type=\"ml.p5.48xlarge\",\n", - " instance_count=2,\n", + " instance_count=4,\n", " ),\n", " role=ROLE_ARN,\n", " base_job_name=\"sft-smtj\",\n", @@ -152,7 +152,7 @@ " s3_output_path=S3_OUTPUT_PATH,\n", " compute=TrainingJobCompute(\n", " instance_type=\"ml.p5.48xlarge\",\n", - " instance_count=2,\n", + " instance_count=4,\n", " ),\n", " role=ROLE_ARN,\n", " recipe=\"my_sft_recipe.yaml\",\n",
