[英]Python scikits - Buffer has wrong number of dimensions (expected 1, got 2)
我正在嘗試此代碼段。 我正在使用scikits.learn 0.8.1
from scikits.learn import linear_model
import numpy as np
num_rows = 10000
X = np.zeros([num_rows,2])
y = np.zeros([num_rows,1])
# assume here I have filled in X and y appropriately with 0s and 1s from the dataset
clf = linear_model.LogisticRegression()
clf.fit(X, y)
我得到了這個 - >
/usr/local/lib/python2.6/dist-packages/scikits/learn/svm/liblinear.so in scikits.learn.svm.liblinear.train_wrap (scikits/learn/svm/liblinear.c:992)()
ValueError: Buffer has wrong number of dimensions (expected 1, got 2)
這里有什么問題?
解決了。 該錯誤是由於:
y = np.zeros([num_rows,1])
應該是:
y = np.zeros([num_rows])
