Hi @xuezhaokun , you need Python 3.

I have the same error with Python 3.5:

$ python3 run.py
Traceback (most recent call last):
  File "run.py", line 3, in <module>
    from minisom import MiniSom
  File "/home/henschjk/.local/lib/python3.5/site-packages/minisom.py", line 23
    progress = f'\r [ {0:{len(str(m))}} / {m} ] {0:3.0f}% ? it/s'
                                                                ^
SyntaxError: invalid syntax

You need Python 3.6 as it supports f-strings.

Yes, I just saw it was introduced in PEP 498.

I think you should add that to the README.

Thank you for the super quick answer!
