TypeError: 'module' object is not callable

Solutions

Install historical versions of keras before 2.1.6[ Releases ]

# pip install https://github.com/keras-team/keras/releases/tag/2.1.6

Problem analysis

1. According to the error log, the module was not found. 2. Check (under the search path) whether there is no such module

>>> import sys
>>> print(sys.path)

3. See if there is a merge.py module (file) in the installation path of keras

$ pip install keras

4. Keras has been installed and from keras.layers import merge has been introduced in the header file. But why not

5. The merge module (file) does exist

6. Open merge.py and find that there is no merge() function, so it will not be called[ Ref]
