[AlaricCheng]

Hi, I'm trying to install hafnian in my ubuntu, but it displays an error

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 3125: ordinal not in range(128)

The full information is

Could you fix it? Thank you!

Hi Alaric,

It looks like the issue might be the default encoding on your system, see this relevant bug report: https://github.com/facebookresearch/DrQA/issues/31

By default, Python 3.6 should be using unicode encoding, but it looks like your system is using ASCII. What is the output of the following command?

>>> import sys
>>> sys.getdefaultencoding()

Thanks for reply. The output is utf-8.

root@e8c01b001d47:/# python3.6
Python 3.6.0 (default, Dec 17 2017, 09:17:58)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.getdefaultencoding()
'utf-8'

Actually, I was using the ubuntu docker image, which might be relavant to this problem. Then I changed to use ubuntu on a virtual machine, and it worked. So personally, this problem has been solved, and you can feel free to close this issue. Though others might need a solution.

Thanks again!
