austinleroy · 2024-04-05T18:00:01Z

While the code in this repo should be fixed, a temporary workaround is to use an older version of the rust toolchain (I had success with rust 1.72.0, installing version 0.13.2):

RUSTUP_TOOLCHAIN=1.72.0 pip install tokenizers==0.13.2

Originally I was trying to install 0.13.3, but ran into issues because the clap dependency requires rust 1.74 or newer.

This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 5 days.

fcolecumberri · 2024-05-12T16:20:29Z

making github-actions close an obvious bug just because no one made comments on it doesn't make the bug go away.

ArthurZucker · 2024-05-17T12:04:46Z

Pretty sure this was fixed

oh i see this fix in lastest code

robert-irelan-tiktokusds · 2024-05-20T23:45:32Z

For future reference, I think this was fixed in commit 4322056

CheaterCodes · 2024-08-13T16:46:40Z

Since this came up in the Rust community discord:

The code is still unsound.

let word = &words[i] as *const _ as *mut Word;

Writing to this pointer is immediate undefined behavior. You may not modify the value behind a &T, unless it somehow involves an UnsafeCell.

I would recommend to instead collect all the indices into a HashSet, and then use words.iter_mut().enumerate().filter() to extract the words.
If this is not acceptable there are other options:

Use a more imperative approach with for loops and appending to a collection
get_many_mut, although unfortunately not stable
Create your own safe get_many_mut by sorting the indices and using split_mut
Implement your own unsafe get_many_mut (not recommended)
