run train.py : At least two variables have the same name

[BoomFan]

Thanks for your work.

I managed to ./make.sh and then run data.py

When I try to run train.py file for KITTI dataset, errors like this shows up:

Use fusion-feature-2fc
Traceback (most recent call last):

ValueError: At least two variables have the same name: MV3D/top_view_rpn/feature-extract-resnet/MV3D/top_view_rpn/feature-extract-resnet/batch_normalization_1/moving_mean/biased

Could anyone offer me a help, please? I'm using Tensorflow 1.8.0 by the way. Is it because of the new version of Tensorflow?

Same problem here... Still working to solve it.

Do you fix the problem, I meet the same problem.
I find where is the problem.
In the src/mv3d.py file, the Net.get_variables() function is wrong.
def get_variables(self, scope_names): variables=[] for scope in scope_names: variables = tf.get_collection(tf.GraphKeys.GLOBAL_VARIABLES, scope=scope) assert len(variables) != 0 variables += variables return variables
the right code is
variable = tf.get_collection(tf.GraphKeys.GLOBAL_VARIABLES, scope=scope) assert len(variable) != 0 variables += variable
pay attention to variables and variable!!!

@hz-fengpeng Thanks a lot!
