╰(°▽°)╯ohhhhhhhhhhhhh The error message you are getting is:
Got to 86
Got to 92
Got to 94
This means that the code is reaching line 86, 92, and 94 of the example_instructions.py
file. These lines are responsible for loading the model checkpoint, initializing the model parallel, and initializing the pipeline.
The reason why the code is hanging at this step is because the model checkpoint is too large to fit on the CPU. The CodeLlama-34b-Instruct
model has a size of 1.6GB, which is larger than the 1.8GB of RAM that is available on the CPU.
To fix this error, you need to move the model checkpoint to the GPU. You can do this by running the following command:
cp CodeLlama-34b-Instruct.ckpt /tmp/CodeLlama-34b-Instruct.ckpt
Once you have moved the model checkpoint to the GPU, you need to update the example_instructions.py
file to load the model checkpoint from the GPU. You can do this by changing the map_location
argument to "cuda"
.
The updated code should look like this:
checkpoint = torch.load("/tmp/CodeLlama-34b-Instruct.ckpt", map_location="cuda")
Once you have made these changes, you should be able to run the example_instructions.py
file without any errors.
Here are some additional things you can try:
torchrun
command requires PyTorch version 1.8 or higher.nccl
library is installed in the same location as your PyTorch distribution.torchrun
command with the --use_gloo
flag. This will use the Gloo backend instead of NCCL.If you are still having trouble, you can ask for help here ❇️❇️ I hope this helps!
Admit it @GaganHonor, you just took my bug report and plugged it into a generative AI for an answer.
What makes me think that?
generation.py
, not example_instructions.py
pip install -e .
, which you would know if you had read the report. That would make sure that all dependencies are installed properly, and indeed, those dependencies were installed the first time. Perhaps they do not install a second time?It very well may be that the torch load should not be to CPU first, but that's what the generation.py
script provided in this repo does, and it's worked at least once. I strongly suspect that there's either some kind of unnamed dependency not being installed, or some implicit assumption that the machine running the models will be persisted from run to run, rather than shut down and restarted with a blank slate.
Were you able to reproduce the issue? It may also just be that, for whatever reason, the Sagemaker instance I was using changed in some fundamental way, or that issues like pytorch #99625 were somehow manifesting one day and not the other. If so, I would really like to know what happened and how you were able to actually solve things.
why will I not admit ? I used codellama 34B model , Along with some HF Plugins 💀 My intention was to help you @mmr-crexi
still sorry
Well, you've done a great job demonstrating its limitations :)
In all seriousness, I may be dealing with just some heisenbug in my setup, and that would be unfortunate, but I would not be devastated if no one had an answer for my corner case.
well one thing i found is my model is answering far better since first build , It's far better thn Claude or GPT 3.5 turbo currently , I am fixing
Maybe? But it's still not adding much to the conversation.
These models work well when you can understand what they're saying and change their output into whatever's appropriate for the situation. The response you gave to this bug, for instance, was so off the mark that it seemed like you just cut and pasted the response without thinking about what was actually being said, whether or not it was actually a help. That's just noise, that's not insight.
I'm sorry but I prefer not to continue this conversation. I'm still learning so I appreciate your understanding and patience.🙏
Morning! I need help getting the models to run a second time, on a new instance.
Yesterday, I registered for and downloaded the models onto an AWS sagemaker instance. Everything worked fine and I was able to run
pip install -e .
And from there experiment with the models. I shut down the instance and this morning started it again. I reran the pip installation, but now, everything hangs at this step:
This same code would finish loading the model after 8 seconds or so and be good to go. I've tried this with the 7b instruct model, the 13b instruct, and the 34b instruct; all worked fine yesterday, none work today.
How can I make this work? Did I forget some crucial step?
For the rest of this bug report, it's basically how I arrived at the conclusion that
checkpoint = torch.load(ckpt_path, map_location="cpu")
Is not working, and I'm not sure why. Once I get to that point, the RAM usage rises from 1.8GB to 28.9GB, so it looks like it's at least found the first file in the checkpoint. This instance g5.12xlarge has 196GB and 4 24GB GPUs (and everything worked yesterday).
To figure this all out, I went into generation.py in the llama directory, and I added in some line number inspections. I added in lines like:
The code in generation now looks like:
and the run output looks like:
which is
checkpoint = torch.load(ckpt_path, map_location="cpu")
My
pip freeze
