2 possibilities of error 1) I think the issue might be you didn't add sdb_path in config file properly ? if not add sdb_path in the config file

2) The data-set you have, does it contain sbd data as well ?

li0128 commented 5 years ago

@pvbhanuteja thank you !

@li0128 - how did you solve the problem?

I am getting a similar error:

I downloaded the dataset from: PASCAL devkit 2012 [Here] and the sbd dataset [Here]

I am using the pretrained model shared here

@mvcaro Do you solve the problem? I am getting a similar error.

jeremyfix commented 5 years ago

I got the same issue; I did also mention the sbd_path in the config file.

pascal_voc_loader can get the sbd_path keyword https://github.com/meetshah1995/pytorch-semseg/blob/801fb200547caa5b0d91b8dde56b837da029f746/ptsemseg/loader/pascal_voc_loader.py#L47

indeed, in the Readme it is mentioned we can provide : in the config file. But I do not see where in the training script these additional key:value arguments are provided to the data_loader https://github.com/meetshah1995/pytorch-semseg/blob/801fb200547caa5b0d91b8dde56b837da029f746/train.py#L44

I suggest a correction in https://github.com/jeremyfix/pytorch-semseg/blob/753ec6847b9921c1318797838e1ec11d5afd88c4/train.py#L41

@mvcaro @wackxu @jeremyfix The code in NO.47 line, "sbd_path=None" was written in the "pascal_voc_loader" file, if you download the project from the github directly. You should code it like this, sbd_path="/../../../benchmark_RELEASE/(the path your saved) ".

dear i'm getting the same error. i don't have sbd data set the folder is bIank. I am running this code on windows 10. i don't know how to define correct path.

bj5546 commented 4 years ago

what can I do if I do not add sbd_path?
