In the source's own words
“You may need rust installed as well, in case tiktoken does not provide a pre-built wheel for your platform.”

Open the original- What it measures
- Whisper depends on the tiktoken package. Installing tiktoken can fail on some Windows setups, which is the build error this note warns about.
- What it does not show
- Whether you need Rust depends on your Python version and on whether a prebuilt wheel exists for it, so the note applies only in some cases.
