錯(cuò)誤原因：GPU資源占用太大

config = tf.ConfigProto(allow_soft_placement=True)
gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=0.7)
config.gpu_options.allow_growth = True

找到如下紅的的這句話，在這之前加上如上三行代碼，在session前約束占用空間。能夠使得tensorflow占用資源降至70%，當(dāng)然也可以改為50%，而不是整個(gè)服務(wù)器GPU

with tf.Session() as sess:
將其改為
with tf.Session(config=config) as sess:

最終改為如下結(jié)構(gòu)就可以啦

config = tf.ConfigProto(allow_soft_placement=True)
gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=0.7)
config.gpu_options.allow_growth = True
with tf.Session(config=config) as sess:
