Vi que tem alguns topicos sobre o assunto. porém, nenhuma sugestão funcionou para mim. o arquivo classificacao.py não executa, tentei instalar o Scipy em diversas maneiras: ou pelo pip ou pelo wheel e não deu certo.

alguém tem o passo a passo que deu certo?

Se for no ubuntu, pra mim funcionou com sudo apt-get install python3-scipy

estou usando python3 se for python 2, acho que a linha abaixo vai funcionar.

sudo apt-get install python-scipy

Se não funcionar. Você pode colar o erro que está aparecendo.

Perdão, não disse qual sistema estou usando. Windows.

ao tentar instalar:

pip install scipy

ele tenta instalar, mas encontra o seguinte erro:

já tentei instalar mais programas

pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

instala todos de boa, só o scipy que não

Gal, na minha máquina só consegui instalar com os binários desse site: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

Como informação adicional, esses binários estão recomendados no próprio site do Scipy (https://scipy.org/install.html)

A instalação é normal:

pip install <pacote baixado>.whl

Oi Gal, se está no Windows recomendo que instale o Anaconda:
