Couldn't run predict_c3d_ucf101.py

[zeynepgokce]

I am new in this area. So, i need your help. The steps i followed : 1) i created dataset folder which has the UCF 101 videos but i opened just one folder with named "walk" under the dataset folder. And there are only 2 videos under this walk folder to test the model. The path is like this ../C3D-tensorflow-master/database/UCF101/walk 2) I followed the all steps on the README. the test.list file as following. /home/zeynep/Desktop/C3D-tensorflow-master/database/UCF101/walk/v_ApplyEyeMakeup_g01_c01 0 /home/zeynep/Desktop/C3D-tensorflow-master/database/UCF101/walk/v_ApplyEyeMakeup_g01_c02 1 3) Then i tried to run predict_c3d_ucf101.py code, i got the error as following.

Number of test videos=2

By the way, i installed the tensorflow with CPU not GPU. When i change the from gpu_num = 2 to gpu_num = 0 , the error like this

Number of test videos=2

ValueError: Shapes (0,) and () are incompatible

What should i do to solve this problem and to got the result ?

I found how to get around this error. Depending on your tf version, tf.concat has swapped the order of the arguments so it should be tf.concat(logits,0)

Yes, the @cristinasegalin is right, and the latest code has supported the TF 1.2 version now.
