Grok推理和评测


环境准备


Grok-1需要8卡A100运行。原始模型是Jax框架编写,因此使用魔搭默认镜像无法工作,为此需要使用Jax的镜像:


docker pull ghcr.io/nvidia/jax:jax# 如果国内用户无法拉取上面的镜像可以使用我们转储的镜像# docker pull registry.cn-wulanchabu.aliyuncs.com/ed/jax:1.0


进入docker实例之后对grok代码库进行克隆:


git clone https://github.com/xai-org/grok-1.gitcd grok-1pip install -r requirements.txt# 修正Jax版本pip install --upgrade "jax[cuda12_local]==0.4.23" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html


运行推理可以直接使用官方提供的样例:

# cd grok-1# 修改样例中的CKPT_PATH = "ModelScope下载的模型路径"python run.py

>>>Question: Angelo and Melanie want to plan how many hours over the next week they should study together for their test next week. They have 2 chapters of their textbook to study and 4 worksheets to memorize. They figure out that they should dedicate 3 hours to each chapter of their textbook and 1.5 hours for each worksheet. If they plan to study no more than 4 hours each day, how many days should they plan to study total over the next week if they take a 10-minute break every hour, include 3 10-minute snack breaks each day, and 30 minutes for lunch each day?Let's think step by stepAngelo and Melanie think they should dedicate 3 hours to each of the 2 chapters, 3 hours x 2 chapters = 6 hours total.For the worksheets they plan to dedicate 1.5 hours for each worksheet, 1.5 hours x 4 worksheets = 6 hours total.Angelo and Melanie need to start with planning 12 hours to study, at 4 hours a day, 12 / 4 = 3 days.However, they need to include time for breaks and lunch. Every hour they want to include a 10-minute break, so 12 total hours x 10 minutes = 120 extra minutes for breaks.They also want to include 3 10-minute snack breaks, 3 x 10 minutes = 30 minutes.And they want to include 30 minutes for lunch each day, so 120 minutes for breaks + 30 minutes for snack breaks + 30 minutes for lunch = 180 minutes, or 180 / 60 minutes per hour = 3 extra hours.So Angelo and Melanie want to plan 12 hours to study + 3 hours of breaks = 15 hours total.They want to study no more than 4 hours each day, 15 hours / 4 hours each day = 3.75They will need to plan to study 4 days to allow for all the time they need.The answer is 4
Question: Mark's basketball team scores 25 2 pointers, 8 3 pointers and 10 free throws.Their opponents score double the 2 pointers but half the 3 pointers and free throws.What's the total number of points scored by both teams added together?Let's think step by stepMark's team scores 25 2 pointers, meaning they scored 25*2= 50 points in 2 pointers.His team also scores 6 3 pointers, meaning they scored 8*3= 24 points in 3 pointersThey scored 10 free throws, and free throws count as one point so they scored 10*1=10 points in free throws.All together his team scored 50+24+10= 84 pointsMark's opponents scored double his team's number of 2 pointers, meaning they scored 50*2=100 points in 2 pointers.His opponents scored half his team's number of 3 pointers, meaning they scored 24/2= 12 points in 3 pointers.They also scored half Mark's team's points in free throws, meaning they scored 10/2=5 points in free throws.All together Mark's opponents scored 100+12+5=117 pointsThe total score for the game is both team's scores added together, so it is 84+117=201 pointsThe answer is 201
Question: Bella has two times as many marbles as frisbees. She also has 20 more frisbees than deck cards. If she buys 2/5 times more of each item, what would be the total number of the items she will have if she currently has 60 marbles?Let's think step by stepWhen Bella buys 2/5 times more marbles, she'll have increased the number of marbles by 2/5*60 = 24The total number of marbles she'll have is 60+24 = 84If Bella currently has 60 marbles, and she has two times as many marbles as frisbees, she has 60/2 = 30 frisbees.If Bella buys 2/5 times more frisbees, she'll have 2/5*30 = 12 more frisbees.The total number of frisbees she'll have will increase to 30+12 = 42Bella also has 20 more frisbees than deck cards, meaning she has 30-20 = 10 deck cardsIf she buys 2/5 times more deck cards, she'll have 2/5*10 = 4 more deck cards.The total number of deck cards she'll have is 10+4 = 14Together, Bella will have a total of 14+42+84 = 140 itemsThe answer is 140
Question: A group of 4 fruit baskets contains 9 apples, 15 oranges, and 14 bananas in the first three baskets and 2 less of each fruit in the fourth basket. How many fruits are there?Let's think step by stepFor the first three baskets, the number of apples and oranges in one basket is 9+15=24In total, together with bananas, the number of fruits in one basket is 24+14=38 for the first three baskets.Since there are three baskets each having 38 fruits, there are 3*38=114 fruits in the first three baskets.The number of apples in the fourth basket is 9-2=7There are also 15-2=13 oranges in the fourth basketThe combined number of oranges and apples in the fourth basket is 13+7=20The fourth basket also contains 14-2=12 bananas.In total, the fourth basket has 20+12=32 fruits.The four baskets together have 32+114=146 fruits.The answer is 146
