Application crashes during training

Hello everyone,

I need to run a lightfm application inside a docker container. This is my Dockerfile:

FROM python:3.6.8-slim

WORKDIR /usr/src/app

RUN apt-get update \
        && apt-get install -y curl apt-transport-https gnupg2 build-essential libxml2 libxslt-dev gcc \
        && curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - \
        && curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list \
        && apt-get update \
        && ACCEPT_EULA=Y apt-get install -y msodbcsql17

RUN apt-get install -y unixodbc-dev

COPY requirements.txt ./
RUN pip install --no-cache-dir -v -r requirements.txt > install.log

ENV TZ=America/Sao_Paulo
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

COPY . .

CMD ["python","-u","main.py"]

When my container is running, then error below is throwed: [9496254.935906] traps: python[45650] trap invalid opcode ip:7f3bf6731489 sp:7ffd515191e0 error:0 in _lightfm_fast_openmp.cpython-36m-x86_64-linux-gnu.so[7f3bf670b000+49000]

This happens when I call method .fit()

It looks like the machine you’re compiling on differs from the machine you are running on. You may want to change the compilation flags to something less performant but more architecture independent. You can do this by making changes to setup.py.

Works @maciejkula . Thanks a lot!
