I have to use Tensorflow 0.11 for this code repo and this is the error I get:

(py35) E:\opensource_codes\gesture_recognition\hand3d-master>python run.py

Please suggest fixes.

The error seems to stem from the line xy_loc.append(tf.concat(0, [x_loc, y_loc]))

I wanted to make sure that I have the same exact subversion of Tensorflow so I did so but still get the above error.

Installed the tensorflow 0.12 and the code worked perfectly with no change:
