Problem 54 error

[yiyuezhuo]

For origin code, I encounter the error.

TypeError: Can't convert 'bytes' object to str implicitly

I read numpy document, and I found

Mote that generators must return byte strings in Python 3k.

However, when I change StringIO to BytesIO and add prefix b before the string. I can get true result.

What python version do you use?

[yiyuezhuo]

Python 3.5.2.

Oh, I considered that io module only existed in python3, but now I have found both StringIO and io module coexisted in python2. So I misunderstant that this code is compatible for python3. It looks actually that it's for python2 specially. This issue can be looked as tiny python 3 compatible problem.
