Hey Juan, It could be because in installing the C -based python modules locally, pip is compiling C code for your system's architecture, which wouldn't translate to the deployed machine. If this is the case, see if the following works as a solution:
You can write a Dockerfile for your Custom Runtime app that will install the requirements when the container image is built, that way it'll use the architecture of the container that will actually run the app. Here's an example Dockerfile from our python custom runtime github repository <https://github.com/GoogleCloudPlatform/python-runtime>: FROM gcr.io/google-appengine/python # Create a virtualenv for dependencies. This isolates these packages from # system-level packages. RUN virtualenv /env # Setting these environment variables are the same as running # source /env/bin/activate. ENV VIRTUAL_ENV /env ENV PATH /env/bin:$PATH # Copy the application's requirements.txt and run pip to install all # dependencies into the virtualenv.*ADD requirements.txt /app/requirements.txt RUN pip install -r /app/requirements.txt* # Add the application source code. ADD . /app # Run a WSGI server to serve the application. gunicorn must be declared as # a dependency in requirements.txt. CMD gunicorn -b :$PORT main:app You can see the lines which install dependencies in bold. Let me know how that works out for you! We could see about getting this caveat for custom runtime deployment and dependencies with c-based python modules documented if that turns out to be the case. In order for me to be able to test and reproduce what you've seen in future, could you also attach the requirements.txt to your reply?
