I am using Tensorflow 1.13.0 version

On requirements.txt the version numbers would be helpfull.

invalid syntax.....

if i train a new model.

how to reload the model in flask?

I get this error:

TensorFlow version in the requirements file should updated to last version otherwise some functions won't work ( like convolution )

when I tried to predict the image I am getting this error , TypeError: a bytes-like object is required, not 'str'
what should I do?

I always have to modify your code to work for me, for example I add ( ) to print "".
