scikit-learnを入れるときに「/usr/bin/ld: -lcblas が見つかりません」と怒られた

Posted at

2度もはまったのでメモ.

結論

状況

CentOSにscikit-learnをpipで入れようとしても以下のように怒られる

g++ -pthread -shared -Wl,-z,relro build/temp.linux-x86_64-2.7/sklearn/svm/liblinear.o build/temp.linux-x86_64-2.7/sklearn/svm/src/liblinear/tron.o build/temp.linux-x86_64-2.7/sklearn/svm/src/liblinear/linear.o -L/usr/lib64/atlas -L/usr/lib64 -Lbuild/temp.linux-x86_64-2.7 -lcblas -lm -lpython2.7 -o build/lib.linux-x86_64-2.7/sklearn/svm/liblinear.so

atlasを入れればいいらしいのだが,入っている模様:

$ yum list | grep atlas
atlas.x86_64                            3.10.1-10.el7                  @base
