Can not use the dataset_loaders

[Thatfreesky]

I clone dataset_loaders repository in my '/home/mountain/GitHub/' dictionary. Then, I use below commands to install the dataset_loaders:

(biomediclasagne) mountain@Mountain:~$ cd GitHub/
(biomediclasagne) mountain@Mountain:~/GitHub$ ls
dataset_loaders
DSB3Tutorial
FC-DenseNet
ipywidgets
Medical-Image-Analysis-IPython-Tutorials
Medical-Image-Analysis-IPython-Tutorials-master.zip
models
SimpleITK-Notebooks
SimpleITKTutorialMICCAI2015
TensorFlow-Examples
tensorflow_notes
(biomediclasagne) mountain@Mountain:~/GitHub$ pip install --user -e dataset_loaders

I have not got any error, but when I try to import some something from dataset_loaders, I got some error:

In [1]: from dataset_loaders.images.camvid import CamvidDataset
fatal: Not a git repository (or any of the parent directories): .git

Hi, For I can not use the dataset_loaders, I decide to read the related source code directly. In the train.py file, I find such code:

train_iter, val_iter, test_iter = load_data(cf.dataset,
                                                train_crop_size=cf.train_crop_size,
                                                batch_size=cf.batch_size,
                                                horizontal_flip=True,
                                                )
n_classes = train_iter.get_n_classes()

Next I go to the data_loader.py, I find the train_iter, val_iter, test_iter all are instances of the CamvidDaraset Class. Then I search this class in the 'dataset_loaders/images/camvid.py' file. But I can not find the get_n_classes() method. In fact in the supper class of CamvidDataset, i.e. ThreadedDataset, I also have not find this method.

Any update since get_n_classes(), get_void_labels are not found. Kindly suggest

Hi @Thatfreesky , I want to train FC-DenseNet, but i don't know how to use dataset_loaders in https://github.com/fvisin/dataset_loaders
So could you please tell me how to use that? Or are there any other solutions for it ?

Thanks a ton!

Hi，

As you see in this issue:https://github.com/fvisin/dataset_loaders/issues/1 I also failed to use the dataset_loaders. So, as I just want to know the implementation of FC-DenseNet, I decided to directly read its source code.

Hi, @Thatfreesky I have trained the code successfully by using fvisin/dataset_loaders, and I put my modified code at #23. You can try it. Hopes that could help you.

你好，正如你在这个问题中看到的：fvisin/dataset_loaders#1 我也没有使用dataset_loaders。所以，因为我只是想知道FC-DenseNet的实现，所以我决定直接阅读它的源代码。在 09/21/2017 19:27，wlwsea 写道：嗨@Thatfreesky，我想训练 FC-DenseNet，但我不知道如何在https://github.com/fvisin/dataset_loaders 中使用 dataset_loaders 所以你能请告诉我如何使用它？或者有其他解决方案吗？万分感谢！— 您收到此消息是因为有人提到了您。直接回复此邮件，在 GitHub 上查看，或将线程静音。
