UnicodeDecodeError: 'utf-8' codec can't decode byte 0x82 in position 7: invalid start byte

I use this code to test pyknp.

from pyknp import Juman
jumanpp = Juman()  # default is JUMAN++: Juman(jumanpp=True). if you use JUMAN, use Juman(jumanpp=False)
result = jumanpp.analysis("お疲れさまです。今週のトップ報告を行います")
for mrph in result.mrph_list(): # 各形態素にアクセス
    print("見出し:%s, 読み:%s, 原形:%s, 品詞:%s, 品詞細分類:%s, 活用型:%s, 活用形:%s, 意味情報:%s, 代表表記:%s" \
            % (mrph.midasi, mrph.yomi, mrph.genkei, mrph.hinsi, mrph.bunrui, mrph.katuyou1, mrph.katuyou2, mrph.imis, mrph.repname))

The error message is:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x82 in position 7: invalid start byte

Thanks for your report.
As written in the document, the next two lines are necessary when you use python2.

# coding: utf-8
from __future__ import unicode_literals

I'll modify the document to be clearer.

I only installed pyknp.I didn't install JUMAN++ and KNP.
I think this is not right.Is this version Python 3.6.4 valid?
In your document,you said python 2.7.15, 3.5.6, 3.6.6 is supported.
Can I use JUMAN++ in win10?
I use Python 3.6.4 |Anaconda 4.3.1

I modify the code like this:

# -*- coding: UTF-8 -*-
from __future__ import unicode_literals
from pyknp import Juman
jumanpp = Juman()  # default is JUMAN++: Juman(jumanpp=True). if you use JUMAN, use Juman(jumanpp=False)
result = jumanpp.analysis("お疲れさまです。今週のトップ報告を行います")
for mrph in result.mrph_list(): # 各形態素にアクセス
    print("見出し:%s, 読み:%s, 原形:%s, 品詞:%s, 品詞細分類:%s, 活用型:%s, 活用形:%s, 意味情報:%s, 代表表記:%s" \
            % (mrph.midasi, mrph.yomi, mrph.genkei, mrph.hinsi, mrph.bunrui, mrph.katuyou1, mrph.katuyou2, mrph.imis, mrph.repname))

But the error still exist.

Traceback (most recent call last):

Where is wrong?

The code is correct, and I can work it in my environment.

As you say, you have to install JUMAN++ (or JUMAN).
Please install it.
FYI, the latest JUMAN++ is here: https://github.com/ku-nlp/jumanpp

Btw, in the latest version in github, we check the existence of JUMAN/KNP.
You can install it as below.

% git clone https://github.com/ku-nlp/pyknp
% cd pyknp
% python setup.py install [--prefix=path]
