TypeError找不到解决方法,求教各位大佬

Keras做图像2分类,一直报错,提示:
TypeError Traceback (most recent call last)
D:\Anaconda3\lib\site-packages\theano\compile\pfunc.py in rebuild_collect_shared(outputs, inputs, replace, updates, rebuild_strict, copy_inputs_over, no_default_updates)
192 update_val = store_into.type.filter_variable(update_val,
--> 193 allow_convert=False)
194 except TypeError:

D:\Anaconda3\lib\site-packages\theano\tensor\type.py in filter_variable(self, other, allow_convert)
233 other=other,
--> 234 self=self))

TypeError: Cannot convert Type TensorType(int64, scalar) (of Variable Elemwise{add,no_inplace}.0) into Type TensorType(int32, scalar). You can try to manually convert Elemwise{add,no_inplace}.0 into a TensorType(int32, scalar).

求教各位大佬,怎么能解决?
