preprocess.py reduce

[charlestondance]

Hi,

I am trying to run preprocess.py and there is an unresolved reference to reduce:
charset = list(reduce(lambda x, y: set(y) | x, structures, set()))

however, if I:

from functools import reduce
I then get the error.

Traceback (most recent call last):
File "preprocess.py", line 88, in

File "preprocess.py", line 60, in main

ok i can turn it into a string this way

string_of_charset = "" for x, i in enumerate(charset): string_of_charset+=str(i[0])

But I get the error

I ran into the same problem. The problem went away when I went to Python2.7 by creating a Python 2.7 environment to run the code in. I did this using

conda create -n Python27 python=2.7

If you want to run in Python 3, this post might be helpful: one of the responders suggests using np.string_() instead of str.

In Python 3.6 I tried:
charset = np.string_(charset)

It did away:
TypeError: No conversion path for dtype: dtype('<U1')

However, it raised:
TypeError: Broadcasting is not supported for complex selections

I have same error ....
TypeError: Broadcasting is not supported for complex selections.
Someone solved?
