## I have the requirements (CPU Upgrade instance):
```auto
cmake==4.0.3
llama_cpp_python==0.3.15
gradio==5.34.2
pypdf==5.9.0
python-docx==1.2.0
pandas==2.3.0
```
When this space builds: [3B Param Basic Chatbot - a Hugging Face Space by david-thrower](https://huggingface.co/spaces/david-thrower/3B-Param-Basic-Chatbot) , the space will get “stuck“ building the wheel for llama.cpp without any feedback in the logs on what is going on:
```auto
Building wheels for collected packages: llama_cpp_python
Building wheel for llama_cpp_python (pyproject.toml): started
# ... never prints another line then a "build error" with no further info
```
I have tried numerous attempts to troubleshoot this:
1. Adding `cmake==4.0.3` to the requirements.
2. Setting the environment variables: FORCE\_CMAKE=1; CMAKE\_ARGS=”-DLLAMA\_OPENBLAS=on”'; PIP\_NO\_CACHE\_DIR=1
3. Nothing seems to fix the problem
The is working like a charm on my laptop (albeit building that wheel did take a few minutes).

I tried it as a last resort, and it worked.
### `app.py`
```py
import subprocess
subprocess.run("pip install -V llama_cpp_python==0.3.15", shell=True)
...
```
### `requirements.txt`
```py

I don’t know, how it is working for you but I am also facing this issue.

There are cases where that method doesn’t work. [In those cases, the most reliable approach is to fork GitHub yourself, create a build wheel, and publish it (though you can certainly use a build wheel created by someone else)](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fusing-llama-cpp-on-spaces%2F172216%2F2). But it’s a real pain…
