The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 32 new columns ({'0', '0.7', '0.15', '0.1875', '0.8', '0.0625', '0.10', '0.24', '0.18', '0.5625', '0.13', '0.9', '0.25', '0.20', '0.1875.1', '0.16', '0.4', '0.12', '0.5', '0.3', '0.27', '0.17', '0.6', '0.11', '0.22', '0.19', '0.21', '0.14', '0.26', '0.2', '0.1', '0.23'}) and 20 missing columns ({'nmed', 'power_normalized', 'area', 'area_normalized', 'power', 'config_0', 'config_5', 'delay', 'delay_normalized', 'config_6', 'config_4', 'config_2', 'sample_id', 'config_3', 'mred', 'config_7', 'config_8', 'mred_normalized', 'config_1', 'nmed_normalized'}).

This happened while the csv dataset builder was generating data using

8-bit GNN Multiplier Configuration PPA Dataset

This repository contains the 8-bit approximate multiplier configuration dataset used by the OpenACM PEA-GNN surrogate, together with the final model weights and helper code needed for reproduction.

Hugging Face Dataset File

  • data/configs_ppa.csv: the main table for datasets.load_dataset. Each row contains sample_id, the multiplier configuration vector, normalized targets, and raw targets (mred, nmed, delay, area, power).

Example:

from datasets import load_dataset

dataset = load_dataset("xuzhuo0417/openacm-gnn-8bit-dataset")
print(dataset["train"][0])

Repository Layout

  • raw/dir_vectors.txt: original 50000 x 9 configuration vectors.
  • raw/label.txt: normalized 50000 x 5 labels used for GNN training.
  • raw/merged.log: unnormalized 50000 x 5 target values.
  • raw/label_minmax.txt: two-row min/max file used to normalize raw/merged.log into raw/label.txt.
  • raw/Graph.csv: fixed graph adjacency matrix for the multiplier graph.
  • metadata/FEATURE.csv: static feature table retained for reproducibility.
  • metadata/graph_edges.csv: edge list exported from raw/Graph.csv; duplicate edges are preserved when the adjacency entry is greater than 1.
  • metadata/dataset_summary.json: compact machine-readable metadata.
  • code/data_pyg.py and code/node_feature.py: scripts for rebuilding the PyTorch Geometric dataset from raw/.
  • code/merge.py and code/minmax.py: scripts documenting target merge and min-max normalization.
  • model/best_model_weights_8.pth: final GNN model weights.
  • model/gnn_predictor.py and model/my_io.py: inference helper files.
  • model/FEATURE.csv and model/label_minmax_8.txt: model-side metadata used by the inference helpers.

Row Ranges

The main HF table keeps all rows in one file. The row ranges used by the local training scripts are:

all: 0:50000 (50000 rows)
train: 0:46000 (46000 rows)
validation: 46000:48000 (2000 rows)
test: 48000:50000 (2000 rows)

Normalization

raw/label.txt is generated from raw/merged.log using min-max normalization:

target_normalized = (target_raw - target_min) / (target_max - target_min + 1e-12)

The min and max values are stored in raw/label_minmax.txt.

Model Weights

The model/ directory contains final model parameters only, without optimizer or epoch state. For model discovery and download statistics on Hugging Face, these files can also be uploaded to a separate model repository and linked to the same paper page.
