__rgb_resnet_v2_50_path__ is defined on line 28.

In Python 2 the string and the r-string behave the same:
$ __python2__
```
>>> '$\Uparrow$ '
'$\\Uparrow$ '
>>> r'$\Uparrow$ '
'$\\Uparrow$ '
>>> '$\Uparrow$ ' == r'$\Uparrow$ '
True
```

In Python 3 the string raises a Syntax Error while the r-string works just like Python 2.
```
>>> '$\Uparrow$ '
  File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 1-2: truncated \UXXXXXXXX escape
>>> r'$\Uparrow$ '
'$\\Uparrow$ '
```
