lore init exception

[asd51731]

hi, I user lore init like 'lore init my_app --python-version=3.6.4 --keras --xgboost' (centos 7)
I catch one exception

Traceback (most recent call last):
File "/home/zhangxiaxu/py36/lib/python3.6/shutil.py", line 544, in move
os.rename(src, real_dst)
FileNotFoundError: [Errno 2] No such file or directory: 'app' -> 'my_app'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/zhangxiaxu/py36/bin/lore", line 11, in
sys.exit(main())
File "/home/zhangxiaxu/py36/lib/python3.6/site-packages/lore/main.py", line 331, in main

with open(src, 'rb') as fsrc:
FileNotFoundError: [Errno 2] No such file or directory: 'app'

Can you give me some help or suggestion?
