Deepseek-based model throws `std::out_of_range` exception on load

[brittlewis12]

Model: OpenCodeInterpreter-DS-6.7B (GGUFs)

This is a deepseek coder instruct-based model, llama arch, but maybe there's something distinct for it that requires special-handling?

Or maybe I did something wrong in converting these files from the original safetensors (used the same build, b2249, for converting, quantizing, and running).

Both -ngl=999 & -ngl=0 produce the same exception:

libc++abi: terminating due to uncaught exception of type std::out_of_range: unordered_map::at: key not found

whoops, it was indeed my mistake in the conversion!

turns out that, while the base instruct model uses a fast tokenizer, this model instead uses the regular llama tokenizer. which means I should've converted with BPE!

reconverted & quantized and what do you know, it runs great.

---

I doubt it's worth investigating the crash on its own given the incorrectly produced model file.

But maybe there could be a way to detect this sort of mistake at conversion time to short circuit this process? Auto vocab-type detection would be beneficial, but that's out of the scope of this issue.

reconverted & quantized and what do you know, it runs great.

Huh, that's surprising. There is a long pending PR that I thought needs to be merged to support DeepSeek models: #5464. It should fix some tokenization problems AFAICT + add conversion

I'm surprised that it worked for you

[brittlewis12]

the updated fp16 conversion and quants just finished uploading: hf link

it does seem to work fine tho! I haven't tested it too extensively, but:

> <|User|>\nwrite fibonacci with a cache hashmap in ruby\n<|Assistant|>\ndef fibonacci(n, cache = {})
  if n == 0 || n == 1
    return n
  end

  unless cache[n]
     cache[n] = fibonacci(n - 1, cache) + fibonacci(n - 2, cache)
  end

  cache[n]
end

# Example usage:
puts fibonacci(5) # Output: 3

This function uses a technique called memoization to store the result of expensive function calls and reusing them when same inputs occur again. This greatly improves performance for recursive algorithms like this one, by reducing redundant calculations. The cache hashmap serves as our "memory" in which we store previously calculated results of fibonacci(n - 1) and fibonacci(n - 2).

The base case is if n equals to 0 or 1, return n itself because the first two numbers in Fibonacci sequence are 0 and 1. If not, it checks whether the result of this function call has been calculated before. If yes, it returns that result directly from the cache hashmap; otherwise, it calculates it by calling fibonacci(n - 1) + fibonacci(n - 2), stores it in the cache hashmap for future use and then return it.

that script just calls main with in-prefix/-suffix, ngl, temp, etc.
