error in creating python environment in anaconda

I download anaconda as the Internet said, and use command 'conda create -n python python=3.6' and it shows "Collecting package metadata (current_repodata.json):failed" and the error report says:

If you go this issue, please try to update the celery version, sometimes it is from your deprecated celery.
I successfully solved this issue after updating to celery==4.4.2.
Also the message queue retry sometimes need to be disable from sql, it might cause some wait lock timeout issue if celery unexpected retry.

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 0: ordinal
not in range(128)
any help would appreciated

Thought you may wanna try these since you are installing it in Hebrew.
1.) Open path "C:\Python27\Lib\" and search for python file "mimetypes.py".
2.) Open and Edit that file. Search for line "default_encoding = sys.getdefaultencoding()"
3.) And add these lines before the searched line in (step 2):
if sys.getdefaultencoding() != 'gbk':
reload(sys)
sys.setdefaultencoding('gbk')

The UnicodeDecode Error might be because you are using wrong version of get-pip.py.
All the strings in Python3 are unicode by default, but in Python2 it is not so.
If you are trying to use get-pip of Python3 with Python2, it might likely be the cause of your error.Try checking for/ obtaining the correct version! :)

This causes the above error:
request = urllib2.Request("http://google.com/foo/", headers={"Accept" : "text/html"})
contents = urllib2.urlopen(request).read()
This does NOT cause the above error. The only difference is the url:
request = urllib2.Request("http://google.com/", headers={"Accept" : "text/html"})
contents = urllib2.urlopen(request).read()
So the problem appears to be anything anything after the domain name. Any ideas why?

I was able to get my problem to go away by just using urllib and not urllib2. I still don't know what caused the problem, but this workout was fine.
url = 'http://google.com/'
f = urllib.urlopen(url, params)
