Proposed fix: [HF tokenizers] Warning 'The current process just got forked, Disabling parallelism to avoid deadlocks' in embedding workers and DataLoaders
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Set TOKENIZERS_PARALLELISM=false (environment variable, before import/fork) or avoid using the tokenizer before forking; it is not a from_pretrained/encode parameter.
Option: Set TOKENIZERS_PARALLELISM explicitly [evidence: official_recommended_action]
Applies when: Any forked worker setup
Steps:
1. export TOKENIZERS_PARALLELISM=false (or set os.environ before importing tokenizers)
2. Alternatively initialize tokenizers inside each worker after fork
Expected: Warning disappears; no deadlock risk.
Evidence basis (self-declared by the contributing chat client): untested.
