# Model Card for Qwen2.5-0.5B-Math-Shepherd-PRM-0.2 |
|
|
|
This model is a fine-tuned version of [Qwen/Qwen2.5-0.5B](https://huggingface.co/Qwen/Qwen2.5-0.5B) on the [trl-lib/math_shepherd](https://huggingface.co/datasets/trl-lib/math_shepherd) dataset. |
|
It has been trained using [TRL](https://github.com/huggingface/trl). |
|
|
|
## Quick start |
|
|
|
Example 1) |
|
|
|
```python |
|
from datasets import load_dataset |
|
from transformers import pipeline |
|
import os |
|
os.environ["HF_HUB_ENABLE_HF_TRANSFER"] = "1" |
|
|
|
model_name = "plaguss/Qwen2.5-0.5B-Math-Shepherd-PRM-0.2" |
|
|
|
pipe = pipeline("token-classification", model=model_name, device="cuda") |
|
dataset = load_dataset("trl-lib/math_shepherd") |
|
example = dataset["test"][10] |
|
|
|
sep = "\n" |
|
|
|
print(sep.join((example["prompt"], *example["completions"]))) |
|
for idx in range(1, len(example["completions"])+1): |
|
text = sep.join((example["prompt"], *example["completions"][0:idx])) + sep |
|
output = pipe(text) |
|
score = float(output[-1]["score"]) |
|
pred = True if output[-1]["entity"] == "LABEL_1" else False |
|
print(f"Step {idx}\tPredicted (score): {pred} ({score:.2f})\tLabel: {example['labels'][idx-1]}") |
|
|

# Grandma gave Bryce and Carter some raisins. Bryce received 6 more raisins than Carter, and Carter received half the number of raisins Bryce received. How many raisins did Bryce receive? |
|
# Step 1: Let $b$ be the number of raisins Bryce received and $c$ be the number of raisins Carter received. |
|
# Step 2: We are given that $b = c + 6$ and $c = \frac{1}{2}b$. |
|
# Step 3: Substituting the second equation into the first equation, we get $b = c + 6 = \frac{1}{2}b + 6$. |
|
# Step 4: Simplifying, we have $b = \frac{1}{2}b + 6$. |
|
# Step 5: Subtracting $\frac{1}{2}b$ from both sides, we get $\frac{1}{2}b - b = 6$. |
|
# Step 6: Simplifying further, we have $\frac{1}{2}b - 2b = 6$. |
|
# Step 7: Combining like terms, we have $-\frac{1}{2}b = 6$. |
|
# Step 8: Multiplying both sides by $-2$, we get $b = -12$. |
|
# Step 9: Therefore, Bryce received $\boxed{-12}$ raisins.The answer is: -12 |
|

# In the Golden State Team, each player earned points. Draymond earned 12 points, Curry earned twice the points as Draymond, Kelly earned 9, Durant earned twice the points as Kelly, Klay earned half the points as Draymond. How many points did the Golden States have in total? |
|
# Step 1: Draymond earned 12 points, Curry earned twice the points as Draymond, which is 2*12 = 24 points. |
|
# Step 2: Kelly earned 9 points, Durant earned twice the points as Kelly, which is 2*9 = 18 points. |
|
# Step 3: Klay earned half the points as Draymond, which is 12/2 = <<12/2=6>>6 points. |
|
# Step 4: The Golden State Team had 12+24+9+18+6 = <<12+24+9+18+6=51>>51 points. The answer is: 51 |
