# TransformerLens environment variables.
# Copy to .env (gitignored) and fill in. Then source before HF-Hub-hitting commands:
#   set -a; source .env; set +a

# HuggingFace access token. Required for gated models: Llama, Mistral, Gemma,
# gated Qwen variants, etc. Create at https://huggingface.co/settings/tokens
HF_TOKEN=

# Optional: retry HuggingFace Hub 429s. Only matters for ad-hoc non-pytest scripts
# (docs build, demo notebooks, one-off `python -m ...` invocations). The pytest
# suite already enables retries unconditionally via tests/conftest.py's
# _enable_hf_retry_for_tests fixture, and CI sets this env var in checks.yml.
# TRANSFORMERLENS_HF_RETRY=1

# Optional: allow MPS device on macOS (off by default to avoid hard-to-debug
# divergence from CUDA / CPU). CI's mps-checks job sets this.
# TRANSFORMERLENS_ALLOW_MPS=1

# Optional: silence the tokenizers parallelism warning when running under uv.
# TOKENIZERS_PARALLELISM=false
