Jupyter Notebook でポチポチ入力しながら読んでる続き。
13章で lifelines ライブラリを使ってる。
ソースのコメントで
# pip install lifelines
と書いてあって、実際ライブラリが見つからないエラーが出る。
import pandas as pd from lifelines import KaplanMeierFitter --------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) <ipython-input-26-83ad2ac062b6> in <module>() 1 import pandas as pd ----> 2 from lifelines import KaplanMeierFitter ModuleNotFoundError: No module named 'lifelines'
いつものパターンね、といつもの通りにやると、、、
C:\WINDOWS\system32>conda install --prefix "C:\Program Files\Anaconda3" lifelines Collecting package metadata: done Solving environment: failed PackagesNotFoundError: The following packages are not available from current channels: - lifelines Current channels: - https://conda.anaconda.org/anaconda-fusion/win-64 - https://conda.anaconda.org/anaconda-fusion/noarch - https://repo.anaconda.com/pkgs/main/win-64 - https://repo.anaconda.com/pkgs/main/noarch - https://repo.anaconda.com/pkgs/free/win-64 - https://repo.anaconda.com/pkgs/free/noarch - https://repo.anaconda.com/pkgs/r/win-64 - https://repo.anaconda.com/pkgs/r/noarch - https://repo.anaconda.com/pkgs/msys2/win-64 - https://repo.anaconda.com/pkgs/msys2/noarch To search for alternate channels that may provide the conda package you're looking for, navigate to https://anaconda.org and use the search bar at the top of the page.

あら?
というわけで、conda lifelines
でググるとここがヒット
なるほど、こうするのね
conda install -c conda-forge --prefix "C:\Program Files\Anaconda3" lifelines
