python - 在 Python 中运行“正常”代码时出现内存错误？

Question

我刚刚尝试了来自 kaggle.com 的 Indian Pima Diabetes Dataset，它有 7 个输入和 2 个输出。我尝试将 Python 中的 ANFIS 包与 Anaconda 和 Jupyter Notebook 一起使用，但即使我只使用 10 或 5 个样本，我也会遇到内存错误。我真的不是编程或计算机科学方面的专家，所以我 - 在阅读了互联网上的很多建议之后 - 完全不知道为什么会发生这种情况以及我如何解决它。所以我希望你们的帮助，伙计们！

这是我的代码：

import numpy as np
diabetes = np.loadtxt("C:/Users/elihe/Documents/Studium Master/Masterarbeit/diabetes.txt", delimiter = ',')
X = diabetes[:5, 0:8]
y = diabetes[:5, 8]

from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=0)

# Input 0: Schwangerschaften - wenig, normal, viel
mf = [[['gaussmf',{'mean':2.,'sigma':1.}], ['gaussmf', {'mean':6., 'sigma': 1.}], ['sigmf', {'b': 9., 'c':1.}]],
     # Input 1: Glukose - niedrig, normal, hoch
     [['gaussmf',{'mean':60.,'sigma':10.}], ['gaussmf',{'mean':120.,'sigma':10.}], ['sigmf', {'b': 160., 'c':0.7}]],
     # Input 2: Blutdruck - niedrig, normal, hoch
     [['gaussmf',{'mean':40.,'sigma':5.}], ['gaussmf',{'mean':80.,'sigma':5.}], ['sigmf', {'b': 100., 'c':0.7}]],
     # Input 3: Hautdicke - dünn, normal, dick
     [['gaussmf',{'mean':30.,'sigma':5.}], ['gaussmf',{'mean':60.,'sigma':5.}], ['sigmf', {'b': 80., 'c':0.7}]],
     # Input 4: Insulin - niedrig, mittel, hoch
     [['gaussmf',{'mean':100.,'sigma':15.}], ['gaussmf',{'mean':300.,'sigma':15.}], ['sigmf', {'b': 600., 'c':0.5}]],
     # Input 5: BMI - niedrig, normal, hoch
     [['gaussmf',{'mean':15.,'sigma':3.}], ['gaussmf',{'mean':30.,'sigma':3.}], ['sigmf', {'b': 40., 'c':1.}]],
     # Input 6: Diabetes-Stammbaum-Funktion - niedriges Risiko, normales Risiko, hohes Risiko
     [['gaussmf',{'mean':0.5,'sigma':0.5}], ['gaussmf',{'mean':1.5,'sigma':0.5}], ['sigmf', {'b': 2., 'c':2.}]],
     # Input 7: Alter - jung, normal, alt
     [['gaussmf',{'mean':30,'sigma':3}], ['gaussmf',{'mean':50,'sigma':4}], ['sigmf', {'b': 70., 'c':1.}]]]

import anfis
from anfis.membership import membershipfunction, mfDerivs

mfc = membershipfunction.MemFuncs(mf)

from anfis import anfis
anf = anfis.ANFIS(X_train, y_train, mfc)

# Fitting
anf.trainHybridJangOffLine(epochs=2)

在这一点上，在一切顺利之后，就会出现这个错误：

我真的不知道，这是怎么回事:(
