Question

当我在Mac终端上运行代码时，发生了以下错误：

Traceback (most recent call last):
  File "data.py", line 20, in <module>
    net.add(Dense(3,10))
  File "/Users/Superman/anaconda/lib/python3.6/site-packages/keras/legacy/interfaces.py", line 43, in wrapper
    str(list(args[1:])))
TypeError: `Dense` can accept only 1 positional arguments ('units',), but you passed the following positional arguments: [3, 10]

这些是我的代码：

import pandas as pd
from random import shuffle
datafile='data.xls'
data=pd.read_excel(datafile)
data=data.as_matrix()
shuffle(data)
p=0.8
train=data[:int(len(data)*p),:]
test=data[int(len(data)*p):,:]

from keras.models import Sequential
from keras.layers.core import Dense,Activation

netfile='net.model'

net=Sequential()
net.add(Dense(3,10))
net.add(Activation('relu'))
net.add(Dense(10,1))
net.add(Activation('sigmoid'))

net.compile（损耗= 'binary_crossentropy'，优化= '亚当'，class_mode = “二进制”）

net.fit(train[:,:3],train[:,3],nb_epoch=1000,batch_size=1)
net.save_weights(netfile)

predict_result=net.predict_classes(train[:,:3]).reshape(len(train))

from cm_plot import*
cm_plot(train[:,3],predict_result).show()

Answer 1

您是否尝试在第一层中定义输入数字： net.add（密集（3，input_shape = 10））

Python：`Dense`只能接受1个位置参数（'units'）
