我正在为我的图像处理项目训练SVM分类器。我已经计算了正面和负面样本的特征，并且我正在给SVM机器。下面是它的代码 -将阵列阵列转换为单个一维矢量
from skimage.feature import local_binary_pattern
from sklearn.svm import LinearSVC
from sklearn.linear_model import LogisticRegression
from sklearn.externals import joblib
import argparse as ap
import glob
import os
import numpy as np
from config import *
from sklearn.datasets import load_svmlight_file
if __name__ == "__main__":
# Parse the command line arguments
parser = ap.ArgumentParser()
parser.add_argument('-p', "--posfeat", help="Path to the positive features directory", required=True)
parser.add_argument('-n', "--negfeat", help="Path to the negative features directory", required=True)
parser.add_argument('-c', "--classifier", help="Classifier to be used", default="LIN_SVM")
args = vars(parser.parse_args())
pos_feat_path = args["posfeat"]
neg_feat_path = args["negfeat"]
# Classifiers supported
clf_type = args['classifier']
fds = []
labels = []
# Load the positive features
for feat_path in glob.glob(os.path.join(pos_feat_path,"*.feat")):
fd = joblib.load(feat_path)
fds.append(fd)
labels.append(1)
# Load the negative features
for feat_path in glob.glob(os.path.join(neg_feat_path,"*.feat")):
fd = joblib.load(feat_path)
fds.append(fd)
labels.append(0)
if clf_type is "LIN_SVM":
clf = LinearSVC()
print "Training a Linear SVM Classifier"
print fds
clf.fit(fds, labels)
# If feature directories don't exist, create them
if not os.path.isdir(os.path.split(model_path)[0]):
os.makedirs(os.path.split(model_path)[0])
joblib.dump(clf, model_path)
print "Classifier saved to {}".format(model_path)
其实这个问题是与clf.fit（）。它接受feature参数作为列向量，但在我的情况下，fds是数组的数组。当我打印的FDS内容，我得到以下输出 -

有一种方法与上述数组的数组转换为单个列向量或列矩阵。
您是否混淆了样本和特征的概念？因为看起来fds列表中的每个对象都是样本（内含功能）。在这种情况下，您可以简单地执行np.array（fds）以获取对象矩阵，其中每行都是数据集的样本，并且每个列都是样本的特征。在其他情况下，您可以使用np.vstack和np.hstack。 –
对不起。它没有解决错误。 –
