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 8 new columns ({'applet_budget_kb', 'throughput_kbps', 'ussd_messages_for_mlkem_pk', 'extra_hybrid_pqc_bytes_per_handshake', 'added_handshake_latency_ms', 'note', 'channel', 'verdict'}) and 8 missing columns ({'secret_or_ciphertext_bytes', 'source', 'signature_bytes', 'algorithm', 'role', 'quantum_safe', 'family', 'public_key_bytes'}).

This happened while the csv dataset builder was generating data using

TL;DR

This dataset is part of the Electric Sheep Africa catalog on Hugging Face. It is indexed for African data discovery with standardized metadata, loading guidance, provenance notes, and analyst-oriented context.

What This Dataset Covers

Public datasets help analysts inspect structured evidence, build reproducible workflows, and compare patterns across domains.

Dataset context from the existing Hugging Face card: Africa PQC Migration Cost (Synthetic) Electric Sheep Africa · Post-Quantum Cryptographic Exposure cluster · dataset DS-7 · v0.1 African digital infrastructure is being recorded by state actors today under the assumption it will be decryptable once quantum computers arrive (2030–2035 per NIST/NCSC/ENISA). This dataset is one dimension of the Africa-specific evidence for that claim. What this dataset answers What does post-quantum migration cost on the constrained… See the full description on the dataset page: https://huggingface.co/datasets/electricsheepafrica/africa-pqc-migration-synthetic.

How To Read This Dataset

  • Start from the repository files and the dataset viewer when available.
  • Treat the README context as a fast orientation layer; confirm variable definitions and units in the data files before modeling.
  • Use explicit country columns when present. When geography is only implied by the title or source metadata, document that assumption in downstream analysis.
  • Preserve missing values until you have a defensible imputation rule.

Usage

from datasets import load_dataset

ds = load_dataset("electricsheepafrica/africa-pqc-migration-synthetic")
print(ds)

split_name = next(iter(ds))
table = ds[split_name]
print(table.features)
print(table[:3])

Convert To Pandas When Tabular

from datasets import Dataset

first_split = ds[next(iter(ds))]
if isinstance(first_split, Dataset):
    df = first_split.to_pandas()
    print(df.head())

Data Quality Notes

  • This card was standardized from the Electric Sheep Africa Hugging Face metadata inventory.
  • Exact schema, row counts, and source files should be inspected in the repository data files.
  • Metadata gaps from the inventory: country, upstream_publisher, modality, format.
  • Do not infer policy meaning from labels alone; confirm definitions, units, and methods in the source material.

Source And Provenance

Suggested Analyses

  • Inspect schema and missingness before modeling.
  • Profile variables by geography, time, and subgroup columns where present.
  • Join with other Electric Sheep Africa datasets using explicit country, year, and indicator fields when available.
  • Build reproducible notebooks that cite both the original source context and the Electric Sheep Africa Hugging Face repo.
