one error

[alexliyang]

when I use labelme_json_to_dataset , error like the following:
(labelme) F:\labelme>python .\scripts\labelme_json_to_dataset .\mytest\test1.json
Traceback (most recent call last):
File ".\scripts\labelme_json_to_dataset", line 45, in
main()
File ".\scripts\labelme_json_to_dataset", line 30, in main
lbl_viz = utils.draw_label(lbl, img, lbl_names)
File "C:\Anaconda2\envs\labelme\lib\site-packages\labelme\utils.py", line 89, in draw_label
label_viz = label2rgb(label, img, n_labels=len(label_names))
File "C:\Anaconda2\envs\labelme\lib\site-packages\labelme\utils.py", line 57, in label2rgb
lbl_viz = alpha * lbl_viz + (1 - alpha) * img_gray
MemoryError

and how much is the max polygen points?

I have correct this problem.
It is just memory over.
change the code like the following:
lbl_viz = lbl_viz.astype(np.float32)
lbl_viz*= alpha
lbl_viz+= (1 - alpha) * img_gray
It runs OK.
