kandi X-RAY | miniFlow Summary
This project is created for learning purpose. The original implementation is python based provided by udacity, added here as well under python/ directory for reference. This implemention doesn't rely on any third party libraries, it also includes "boston house price" [sample data embedded in the java file. No need to install any environment or tools, Just click run in Java IDE. As java enforce the data type, so it is easier to read through and understand the data type of "values" or "gradients", which I found often confusing in python, as they are sometimes means matrix, and sometimes are vectors or scalars. Please also notice for "gradients" map, the key and value have same shape. In this implementation, I use "Value" class to represent any matrix and vector and scalar. Inside, Value is always a 2 dimensional double array, with row and col. For scalar, it is a "1 X 1" matrix, for vector, it is "1 X N" matrix. I found this is better way to represent value and express the operation among them than to have super and sub class. I also use "dot" for matrix tranformation, while "multiple" mean multiple two elements from corresponding location. eg: [1, 2] dot Transpose([1, 2]) = [5], while [1, 2] * [1, 2] = [1, 4]. "A dot B" requires first matrix A number of colunms equals B number of rows. "A * B" requires A and B have same number of rows and columns. Another important tricks I found in this implmentation is to allow processing multiple samples at the same time, by redefining the meaning of matrix "add", eg, you can add bias b to each row of X dot W. For details, please refer Value.java class.

QUESTION
I am trying to build a Django app that would use Keras models to make recommendations. Right now I'm trying to use one custom container that would hold both Django and Keras. Here's the Dockerfile I've written.
...ANSWER
Answered 2019-Jan-02 at 22:56It looks like tensorflow only publishes wheels (and only up to 3.6), and Alpine linux is not manylinux1
-compatible due to its use of musl
instead of glibc
. Because of this, pip
cannot find a suitable installation candidate and fails. Your best options are probably to build from source or change your base image.

Install miniFlow
You can use miniFlow like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the miniFlow component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
