问题

<ERROR: moduleinvoker: module name: dl_layer_lstm, module version: v1, trackeback: RuntimeError: Physical devices cannot be modified after being initialized>

请问是什么原因？配置了一块GPU，重启了开发环境也不行，一直提示这个错误

解答

您好，麻烦您这边重启下内核。然后运行下面的程序的第一个cell看看可不可以成功。可以成功在运行画布。

或者如下运行代码

import tensorflow as tf 
gpus = tf.config.list_physical_devices('GPU') 
if gpus: 
try: 
# Currently, memory growth needs to be the same across GPUs 
for gpu in gpus: 
tf.config.experimental.set_memory_growth(gpu, True) 
logical_gpus = tf.config.list_logical_devices('GPU') 
print(len(gpus), "Physical GPUs,", len(logical_gpus), "Logical GPUs") 
except RuntimeError as e: 
# Memory growth must be set before GPUs have been initialized 
print(e)
