My code works without problems despite there are red wavy lines under the code and under the screen shoot, and the functions have no parameter hints.
cheers!
Hi @Liu_Panpan
Welcome to the TensorFlow Forum!
I tried replicating the same error using the latest TensorFlow version in Pycharm and did find the red underline issue.(Please have look at the below screenshot).
Please try again by installing the latest TensorFlow version and let us know if the issue still persists. Thank you.
