GluonCV dem_ufc101 attribute error list object has no shape

I ran all the gluoncv examples without error except this one. When the transform function is applied I receive: AttributeError list object has no attribute shape. Even the dive_deep_ucf101 trains for the 3 epochs without error.
All pip3 installs:
cuda 10.1
mxnet 1.5.1.post0
gluoncv 0.5.0

Solve upgraded to latest gluoncv==0.6.0b20191010 and it worked.

Hi @hskramer,
Indeed version of gluoncv depends on specific version of mxnet. Also the tutorials displayed on the website are based off current master.
