OSError: libgomp.so.1: cannot open shared object file: No such file or directory

Could an admin please take a look at my (python) submission #110276? With respect to environments/config, I claim that the only difference over the starter kit code is that I’ve imported lightgbm. Everything works in the notebook, but the submission fails citing “OSError: libgomp.so.1: cannot open shared object file: No such file or directory”.

I’d appreciate some further insight on this one :slight_smile:

Hello @tom_snowdon

It looks like lightgbm requires libgomp to be installed. In the notebook, can you try adding an APT_PACKAGES attribute to your Config class?

It should look similar to this

class Config:
    'numpy',  # you can define versions as well, numpy==0.19.2
    'scikit-learn==' + sklearn.__version__,

Try restarting your runtime if it doesn’t work the first time. Hope this helps! :slight_smile:


That works!

Thanks for your help (and swift reply)

how to install this library “libgomp1” in the zip submission?

Hello @alarih

You can add an apt.txt file (similar to requirements.txt). You can define the packages that need to be installed via apt-get install command in this file.

To confirm, that is simply a file name apt.txt with the content:


Yes that’s right. Any other APT packages would be on a new line in the same file :+1:
