关于keras框架的问题?????

Question

Traceback (most recent call last):
File "F:/python3.5/projects/untitled1/CNN/MN/test2.py", line 11, in
from keras.models import Sequential
File "F:\python3.5\lib\site-packages\keras__init__.py", line 3, in
from . import utils
File "F:\python3.5\lib\site-packages\keras\utils__init__.py", line 6, in
from . import conv_utils
File "F:\python3.5\lib\site-packages\keras\utils\conv_utils.py", line 9, in
from .. import backend as K
File "F:\python3.5\lib\site-packages\keras\backend__init__.py", line 72, in
assert _backend in {'theano', 'tensorflow', 'cntk'}
AssertionError

为什么kears出现这种错误  后端的tensorflow也配置了  
求大神解答一下

Answer 1

~\keras\backend__init__.py
70行改为
_backend = os.environ['KERAS_BACKEND']='tensorflow'
并把
assert _backend in {'tensorflow','theano','cntk'}
注释掉
