Build a Python machine learning environment with a container

Build a Python machine learning environment with a container

Build a Python machine learning environment in a container on your laptop.

This time, we will build a container that can use fastText and Python3 mainly as an environment for text-based machine learning.

image

--For execution (learning and verification), log in to the machine learning container with a shell and execute fastText and Python3. --Mount the source code and learning files on the folder on your PC. --The editor uses Visual Studio Code.

environment

• Windows 10 Pro
  • Memory : 8GB
• Docker Desktop for Windows

Launch the base container image

First, start the base container image. It is better to keep the execution command here the same as the command to execute the built container image. This time we will build fastText inside the container, so we will use the CentOS image.

1. Execute the base command with the following command.

docker run -it -v /c/temp/data:/data --rm centos:centos8 /bin/bash

Install and verify what you need little by little

You can build with Dockerfile from the beginning, but you may get an installation error. This work is done to gradually verify the environment.

Python installation-fastText build

1. Execute the following command. * Wait for a while with "Running setup.py install for fasttext ..." after executing pip3 install.

dnf -y install python36
yum install -y git make gcc gcc-c++
yum install -y python36-devel
cd /usr/local/src
git clone https://github.com/facebookresearch/fastText.git
cd fastText
pip3 install .

2. Check if it can be imported as a python package. Execute the following command and if there are no errors, it is OK.

python3
import fasttext
exit()

4. Save the container you have worked on with docker export. From the next time onwards, you can continue working from here with docker import.

docker export {Image ID} > {file name}.tar

Install machine learning package

Install the standard package.

1. Execute the following command.

pip3 install numpy pandas matplotlib scikit-learn

Install Japanese processing package

Install the packages required for Japanese processing. The dictionary is not required, so you can skip it.

1. Execute the following command.

rpm -ivh http://packages.groonga.org/centos/groonga-release-1.1.0-1.noarch.rpm
yum -y makecache
yum -y install mecab mecab-ipadic
yum -y install --nogpgcheck mecab-devel
pip3 install mecab-python3 neologdn emoji

2. Install the dictionary (install diffutils patch which file openssl as it is required by the installation script)

yum install -y diffutils patch which file openssl

cd /usr/local/src
git clone --depth 1 https://github.com/neologd/mecab-ipadic-neologd.git
cd mecab-ipadic-neologd
./bin/install-mecab-ipadic-neologd -n -y

Export environment

This time I want to use it for personal use and always use the new package version, so I will export the environment to the work Dockerfile so far.

• By the way, the file that docker exported in the state so far was 1.7GB.

--Points when creating a Dockerfile --Use WORKDIR instead of cd (cd cannot be used in Dockerfile) --The command should be executed by bash. --The dictionary is commented out. (Because it takes time to build)

Dockerfile

FROM centos:centos8

SHELL ["/bin/bash", "-c"]

RUN dnf -y install python36

#fastText Build

RUN yum install -y python36-devel

RUN pip3 install mecab-python3 neologdn emoji

#Install Mecab Dictionary

# RUN yum install -y diffutils patch which file openssl
# 
# WORKDIR /usr/local/src
# RUN git clone --depth 1 https://github.com/neologd/mecab-ipadic-neologd.git
# WORKDIR /usr/local/src/mecab-ipadic-neologd
# RUN ./bin/install-mecab-ipadic-neologd -n -y

Build and boot confirmation

1. Build using Dockerfile.

docker build -t fasttext/centos8:v1.0 .

2. Confirm that it can be started with the following command.

docker run -it -v /c/temp/data:/data --rm fasttext/centos8:v1.0 /bin/bash

Summary

By following the steps below, you have built a Python machine learning environment in a container on your laptop.

1. Launch the base container image
2. Install and verify what you need little by little
3. Export the container image

With remote work, it was not possible to always connect to the in-house VPN, and development work on the development server was difficult, but this environment solved it.

Since it takes time to learn on a notebook PC, there are problems such as "resources are occupied for learning" and "cannot shut down", but if the same container is loaded in advance on the development server, "less on a notebook PC" You can solve this problem by following the procedure "Check operation with epoch → Increase epoch on development server and learn". It is also possible to hook the commit of the source code and automatically run the learning on the development server. I will summarize the article separately about that.
