Hi Shara, The example dockerfile installs the base requirements for Ubuntu but then we use the build_venv.sh (or build_conda.sh) to build the Arrow CPP library and then pyarrow [1].
>From the error it seems you did not build Arrow CPP as libarrow.so can't be found. Can you try following the recipe on the provided sh file? Kind regards, Raúl [1] https://github.com/apache/arrow/blob/main/python/examples/minimal_build/build_venv.sh El mar, 21 nov 2023 a las 23:05, Akshara Sadheesh (<sharasadhe...@gmail.com>) escribió: > > Hi, > > I have been trying to use the minimal_build for python with the > provided examples Dockerfile.ubuntu for my lambda layers since it has > a 250 MB limit.
