Hi, I’m trying to upload my app on Spaces. This app built with gradio works on my computer but I have a build error without any explanation (no log). So I’m interested if anyone knows something about this issue. Thanks in advance [https://huggingface.co/spaces/mikachou/dog-breed-detection](https://huggingface.co/spaces/mikachou/dog-breed-detection) ---

Finally I have a “ValueError: bad marshal data (unknown type code)” due to the fact that I have trained my model with tf on python 3.7 (Google colab) and the execution environment is in python 3.8 (it works at home with pyenv and python 3.7) thanks ---

hi @mikachou I see you’re now using the [`python_version`](https://huggingface.co/docs/hub/spaces-config-reference#:~:text=streamlit%2520or%2520static.-,python_version,-%253A%2520string) parameter Did you succeed running your project? ---

Hi, Sorry for late answer. I put `python_version` parameter, it worked yesterday. But today I changed some files in project, and parameters in `README.md`. I also changes the space url from `/dog-breed-detection` to `/dog-breed-identification`. Anyway it stopped working. For today I’ve always had the same message : ```auto Build error build failed with exit code: 1, message: None ``` with no log My app works on local machine. Please help me! Thanks in advance. ---

sorry @mikacho, it seems like we’re having issues on our infra, which is affecting Spaces. You could try a factory reboot meanwhile. ---

no pb, I already tried factory reboot many times, I will try it again. keep finger croosed 🤞 hope it will work ---

OK I’ve just tried factory reboot again twice, each time after a few second I’ve had the problem : build error, message:None, no logs ---

@radames OK I made many factory reboot, and I’ve just done another one earlier this morning and this one finally worked. Is this case (build error; message: None; no log) likely to occur again in future? Thank you ---

Issue were linked to an outage on an underlying service of the space build process. The build error case with no logs is not supposed to happen in the nominal cases. ---

@chris-rannou thanks for answer I hope it won’t happen again 🤞 I would like to make later further modifications on code but now I fear a bit about deployments 😬 I’ll do the modifications another time. Thanks ---

Hi everyone! I am having the same problem [here](https://huggingface.co/spaces/slone/myv-translit/discussions/1) (also reported [here](https://discuss.huggingface.co/t/build-error-when-accessing-space-app/14057/4)). After a forced rebuild, the space works for a while, but then the “Build error” with empty logs happens again. Is there a way to debug or fix it?
