2017-08-07 16:52:42,418 [theano.sandbox.cuda ] [ERROR   ] ERROR: Not using GPU. Initialisation of device gpu failed:
initCnmem: cnmemInit call failed! Reason=CNMEM_STATUS_OUT_OF_MEMORY. numdev=1

虽然backtrace有'HINTS'调整

['exception_verbosity']='high'

或者

['optimizer'] = 'fast_compile' / 'None'

但是并不起作用，可以通过调整.当前用户根目录下　~.theanorc 文件设置解决

cnmem = 0.45

本机是把这个值一直往下调调到0.45就不报错了

但是这个值并不影响计算时真实的显存使用率，如果担心影响，可以设置

learner['mlp']['keras']['backend_parameters']['cnmem'] = 0.9
