Cache entry deserialization failed, entry ignored

[Nalin Mathur]

Hello, 

I am new to Keras and have just installed it into a virtualenv where I had tensorflow installed. 

While installing keras with the statement: 

pip3 install keras 

I got the following error message:

'Cache entry deserialization failed, entry ignored'

Can you please tell me the meaning of this and why it's occurred ? I do not know about the severity of it and whether it may lead to problems in usage in the future.
