ImportError: cannot import name '_ccallback_c'

Question

Initially I was getting this error (No Module name was found scipy) So I installed a Scipy wheel file. Now I don\'t get the same error any more but I get cannot import

Answer 1

I first had the error with scipy. So I ran the command python -m pip install -user numpy scipy matplotlib ipython jupyter pandas sympy noseand it worked perfectly. I was installing everything with pip, so I decided to use Anaconda. I installed and checked to add to the PATH. From there, the same code that was executed before normally stopped working and displays the error similar to that of the question. I uninstalled Anaconda and it is now working again.

Erro:

$ winpty python ia.py

Código:

from sklearn import tree #importando a biblioteca e a árvore p/ o classificador
#COLLLECT TRAINING DATA
features = [[140,1],[130,1],[150,0],[170,0]]
labels = [0,0,1,1]
# TRAIN CLASSIFIER 
clf = tree.DecisionTreeClassifier() #Classificador
clf = clf.fit(features, labels) #algoritmo de decisão p/ encontrar padrões
#MAKE PREDICTIONS
print(clf.predict([[160, 0]])) #entrada de dados para o tratamento
