【问题描述】:
我创建了 .model 格式的机器学习模型。我需要加载我的机器学习模型以便从模型中获取权重。但是每当我尝试加载模型时,它都会显示错误:
Pa1 instance has no attribute 'load'`
我所有的模型(Pa1、Ogd、Arow)都会遇到这种情况
这是我的程序的一部分:
global clfs
clfs = [Pa1(), Ogd(), Arow()] #this is my model pool
print 'model pool size: ', len(clfs)
filedir = '/home/myfile'
for i in xrange(len(clfs)): # for each model in the model pool
clfs[i].load( filedir + '_' + str(i) + '.model')
# get original model weight
w = clfs[i].coef_[1:]
weights = []
weight = [] # [i][j]: i = model index, j = feature index
for w_num in xrange(len(w)):
weight.append(w[w_num])
weights.append(weight)
我保存模型的方式:
for i in xrange(len(clfs)): # i = every model in model pool
print clfs[i]
print 'training'
train_accuracy=clfs[i].fit(X_train,Y_train)
ori_train_acc.append(train_accuracy)
clfs[i].save( filedir + '_' + str(i) + '.model')
这是我的 myfile_1.model(只是其中的一部分,因为它太长了)

我正在使用 python 2.7。有什么解决办法吗?我应该改变保存模型的方式吗?
