bug5-tensorflow.python.framework.errors_impl.UnknownError: Failed to get convolution algorithm_ds-math-sub-underflow

完整错误：
tensorflow.python.framework.errors_impl.UnknownError: Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above. [Op:Conv2D]
使用背景：
**

• win10
• Anaconda
• pycharm
• cuda10.0
• cuDNN 7.6.4
• tensorflow-gpu 2.0

解决方案
在代码前加这一段，具体原理模棱两可，无非就是改变了显卡内存的分配

from tensorflow.compat.v1 import ConfigProto
from tensorflow.compat.v1 import InteractiveSession
config = ConfigProto()
config.gpu_options.allow_growth = True
session = InteractiveSession(config=config)
