Thanks for your awesome code share!

I run the sem_seg code following readme step by step, but when I runpython train.py --log_dir log6 --test_area 6, there is an error:KeyError: "Unable to open object (object 'data' doesn't exist)", here is details:

Traceback (most recent call last):
  File "train.py", line 70, in <module>
    data_batch, label_batch = provider.loadDataFile(h5_filename)
  File "/usr/Downloads/pointnet/provider.py", line 97, in loadDataFile
    return load_h5(filename)
  File "/usr/Downloads/pointnet/provider.py", line 92, in load_h5
    data = f['data'][:]

KeyError: "Unable to open object (object 'data' doesn't exist)"

I run the code in tensorflow docker 1.7.1-devel-gpu of Python 2.7, and I solve all the problem of dependency.

Looking forward to your response, thanks a lot!

Have you downloaded or prepared your hdf5 files properly? Usually there will be a folder named "indoor3d_sem_seg_hdf5_data" in folder sem_seg. And there should be two separate parts "data" and "label" in each .h5 file. I would recommend you to check the contents of your hdf5 files.

When you run python train.py for the first time it downloads the data for you I have the same error, when running it locally (with sudo privileges) it works, but on a remote server with a virtualenv I have the same error like qixuxiang

I have the same question while using data from indoor3d_sem_seg_hdf5_data

I faced this issue too. This can happen if the xxx.h5 files are broken. Try to download the dataset again and train. This worked for me.
