error happens when I run labelme_json_to_dataset

[zhangfanqie]

I cd into my folder where include image files and its corresponding  json files(built success)
But error happens when I run  labelme_json_to_dataset imageName.json in the terminal

OS:ubuntu 14.04

Traceback (most recent call last):
  File "/usr/local/bin/labelme_json_to_dataset", line 45, in <module>
    main()
  File "/usr/local/bin/labelme_json_to_dataset", line 27, in main
    img = utils.img_b64_to_array(data['imageData'])
  File "/usr/local/lib/python2.7/dist-packages/labelme/utils.py", line 36, in img_b64_to_array
    img_arr = np.array(PIL.Image.open(f))
  File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 2028, in open
    raise IOError("cannot identify image file")
IOError: cannot identify image file

Is this a bug of the source code?

Have you tried with the sample jso filen?

Yes,I've tried your sample,but got the same error.
I tried to debug and build a project in PyCharm IDE ,but I got this

Traceback (most recent call last):

RuntimeError: the sip module implements API v11.0 but the PyQt5.QtCore module requires API v11.3

I follow the instruction you show,but why there's pyqt5.qtcore as above instead pyqt4.I'm really confused.
I try to use labelme to get label files which will be used in mxnet, fcn to train my datasets.Is there other solutions to process image to do image segmentation

[wkentaro]

It may be problem with integration with PyCharm IDE, and I'm not sure how to fix it.
You can try on command line or cleaned ubuntu 14.04 if you already installed pyqt5.
