running error from "python test_fcn32_vgg.py"

[amiltonwong]

Hi, all,

I got the following error when running "python test_fcn32_vgg.py"

InternalError (see above for traceback): Dst tensor is not initialized.
	 [[Node: fc6/weights/Initializer/Const = Const[_class=["loc:@fc6/weights"], dtype=DT_FLOAT, value=Tensor<type: float shape: [7,7,512,4096] values: [[[1.9745843e-05 0.00035308721 -0.0018327669]]]...>, _device="/job:localhost/replica:0/task:0/gpu:0"]()]]

My version of tf is r0.12.1 and I checkout the package (bf9400c) already. Could someone suggest me how to fix it?

THX!

I do not get this error using the pip build version '0.12.1' and commit (bf9400c). I suspect this is a tensorflow error. I would suggest trying to install tf version 1 in a virtualenv and test whether it still occurs.

Thanks @MarvinTeichmann.
Finally , I upgrade to version 1. And it works now :)

One info to supplement:
I test both versions: tf1.0.0a0 and tf1.0.0rc0. And found that only version 1.0.0a0 works. For version 1.0.0rc0, it will prompt "tf.concat_v2" error:

Thanks, I have addressed this in the ReadME.

Ok, I have updated the code to be compatible with the newest rc version. So since commit ba49956, the tensorflow version to use is tf1.0rc0. I properly should not have gone done the path to upgrade to 1.0 that early. Did not expect so many breaking changes...
