Hello,
I have one problem when running your code in train.py, line 60.

discr_loss_weight = discriminator.net._blob_loss_weights[discriminator.net._blob_names_index['discr_loss']]

I got AttributeError, 'Net' object has no attribute '_blob_names_index'
How can I run this code correctly?

samson-wang commented

@vex1286
You should use the https://github.com/dosovits/caffe-fr-chairs/tree/deepsim branch of caffe.
Just checkout the deepsim branch of caffe, and compile it. Then export PYTHONPATH=/path/to/deepsim/caffe/python:$PYTHONPATH. The train.py should be running correctly then.

You'd better read the Dependency section of the readme again.

@samson-wang
Thank you for your reply, I will use this branch and try again.

samson-wang commented

@vex1286
Have you got the train running?

vex1286 commented

@samson-wang
Yep. It works well now. Thank you very much.

Hi,

I tried to merge Dosovitskiy's code with Caffe on Windows and got this error when I tried to do training.

Has this merge been done before? I thought there aren't too much work. But obviously, I have missed a chunk of it. I could not find where "_blob_names_index" is defined. Can someone give me a pointer?

samson-wang commented

@pauldelmusica It's in python/caffe/_caffe.cpp

pauldelmusica commented

Thanks! It is training now.

Hi,

I still have problem while training.

My environment is Ubuntu 16, Cuda 8.0 , cudnn 5.1

I clone caffe from deepsim and switch to the branch.

To compile deepsim I disable cudnn and compiled well.

But the problem still occured.

Could you help me solve the problem?

samson-wang commented

@ming1144 Could you post your error message?
You'd better print your caffe.__file__. And make sure you are using the right caffe lib.

python train.py error msg:
Traceback (most recent call last):
File "train.py", line 60, in
discr_loss_weight = discriminator.net._blob_loss_weights[discriminator.net._blob_names_index['discr_loss']]
AttributeError: 'Net' object has no attribute '_blob_names_index'

deepsim error msg:
print caffe.file
/home/mmplab/git/caffe-dcgan/python/caffe/init.pyc

I've replaced deepsim name as caffe-dcgan

samson-wang commented

@ming1144 It's weird.
caffe.file is an invalid attribute.
It should be print caffe.__file__
and output should be /home/core/deploy/caffe/python/caffe/__init__.py

You can search in /home/mmplab/git/caffe-dcgan/python/caffe/_caffe.cpp to make sure that _blob_names_index exists.

ming1144 commented

@samson-wang
You are right.

_blob_names_index didn't show in _caffe.cpp

And the reason it didn't exist is that I clone the master branch of deepsim
_blob_names_index only appear in deepsim branch

This problem has been done.
Thanks to your supply.

i try to solve this in windows but the same problem it show

discr_loss_weight = discriminator.net._blob_loss_weights[discriminator.net._blob_names_index['discr_loss']]
AttributeError: 'Net' object has no attribute '_blob_names_index'
