What is the type of your dataset? (i.e., train
). Method scatter_dataset
requires it to be picklable.
@iwiwi : so according to @yuyu2172 in the related issue on chainercv.
The error occurred because function objects can not be pickled. We will look into a way to fix this issue. Thank you very much for reporting.
As can be seen on line 91 in this gist the chainercv TransformDataset
and transform
functions wrap the dataset and carry out online data-augmentation. It seems they can't be pickled.
I see. Let me close this issue here, and let us continue the discussion at ChainerCV repository. Thanks!
Hi,
I am trying to use chainercv with chainermn.
I used chainercv with some of my new projects and when i attempt to distribute training using chainermn, I receive the following error from the
scatter_dataset
method. All i am doing is applying arandom_flip
transform to the training data. I get the error for all my projects that use chainercv and have replicated it using the chainermn mnist example file .I'm not sure as to where to raise this issue so I have raised it in both the chainercv and chainermn repos.
