Keras | TypeError: __init__() missing 1 required positional argument: 'nb_col'
提问by Gertjan Brouwer
I am currently trying to implement this tutorial code into my own convnet.py but I get an error. Tutorial
我目前正在尝试将本教程代码实现到我自己的 convnet.py 中，但出现错误。教程
This is the full error:
这是完整的错误：
Traceback (most recent call last):
File "convnet.py", line 6, in <module>
model.add(Conv2D(32, (3, 3), input_shape=(3, 150, 150)))
TypeError: __init__() missing 1 required positional argument: 'nb_col'
Here are the first 10 lines on which the program goes wrong:
以下是程序出错的前 10 行：
from keras.models import Sequential
from keras.layers import Conv2D, MaxPooling2D
from keras.layers import Activation, Dropout, Flatten, Dense
model = Sequential()
model.add(Conv2D(32, (3, 3), input_shape=(3, 150, 150)))
model.add(Activation('relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
The code is located in the file convnet.py and I run the file like this:
python convnet.py
该代码位于文件 convnet.py 中，我像这样运行该文件：
python convnet.py

You are probably using an old version of Keras that had the following signature:
您可能正在使用具有以下签名的旧版 Keras：
Conv2D(self, nb_filter, nb_row, nb_col, ...)
With this old version, you would define the conv layer as:
使用这个旧版本，您可以将 conv 层定义为：
model.add(Conv2D(32, 3, 3, input_shape=(3, 150, 150)))
You can check the version you are using with:
您可以检查您正在使用的版本：
import keras
print(keras.__version__)
I suggest that you update your Keras.
我建议你更新你的 Keras。
