データサイエンティスト100本ノックでSQLがエラーになったときの対処法

Posted at

起こった事象

データサイエンティスト100本ノックをやろうとした時にSQL文が打てなくなった。

解決法

Dockerfile.notebookに以下を追加してコンテナをビルドし直す

FROM jupyter/datascience-notebook:python-3.8.6
#FROM jupyter/datascience-notebook:d53a302fbcd0
USER root
ENV DEBCONF_NOWARNINGS yes
RUN apt-get update
RUN apt-get install -y libpq-dev
USER jovyan
RUN pip install --upgrade pip
RUN pip install --upgrade setuptools
RUN pip install --no-cache-dir ipython-sql==0.3.9
RUN pip install --no-cache-dir psycopg2==2.8.5
RUN pip install --no-cache-dir imblearn==0.0
RUN pip install ipython-sql ←この一文を追加
RUN Rscript -e "install.packages(c('DBI', 'RPostgreSQL', 'rsample'), dependencies = TRUE, error = TRUE, repos='https://cran.r-project.org')"
#RUN Rscript -e "install.packages(c('DBI', 'RPostgreSQL', 'recipes'), dependencies = TRUE, error = TRUE, repos='https://cran.r-project.org')"

これを追加することでSQL文を打てるようになります。
