conda create -n tensorflow python=2.7 anaconda
But it is missing of dbm module.

Unfortunately, I still have the same error when import dbm.
Any help is much appreciated.
Thanks.
AFAIK, there are no Anaconda (or Conda Forge) Python 2.7 builds that support the dbm module for Linux (e.g., see this issue). The anaconda::python-gdbm package should provide the functionality, but the import will be:
import gdbm

I'm writing a script in python to update some YAML config files containing jinja2. I found this answer showing how to do it using ruamel.yaml and ruamel.yaml.jinja2 packages and it works absolutely fine on windows10 using this configuration:
$ python -V
Python 2.7.5
$ python -m pip list
[...]
ruamel.ordereddict 0.4.13
ruamel.yaml 0.15.94
ruamel.yaml.jinja2 0.2.2
[...]
and this code:
from ruamel.yaml import YAML
yamlLoader = YAML(typ='jinja2')
But when I try to use it on a CentOS virtual machine, which is the target environment for this script, I get this error:
File "/opt/salt/mig/cnamts_migrate.py", line 17, in <module>
yamlLoader = YAML(typ='jinja2')
File "/usr/lib64/python2.7/site-packages/ruamel/yaml/main.py", line 138, in __init__
'typ "{}"not recognised (need to install plug-in?)'.format(self.typ)
NotImplementedError: typ "jinja2"not recognised (need to install plug-in?)
I can't find any difference in neither Python configuration nor packages' version.
On CentOS VM:
$ python -V
Python 2.7.5
$ pip list
Package Version
---------------------------- -----------
pip 19.1
ruamel.ordereddict 0.4.13
ruamel.yaml 0.15.94
ruamel.yaml.jinja2 0.2.2

This path
/usr/lib64/python2.7/site-packages/ruamel/yaml/main.py
in the error message gives me the impression that you are using a system wide Python installation. You should (IMHO even in a VM) use python virtualenv for any utility (and preferaby one per non-related utility). You don't show the output of pip for your CentOS machine, which is way more interesting than the one on your Windows box.

I ran into the same error message. but with python3.6.
The fix for me was to pip instead of easy_install.

I installed anaconda2 over python 2.7 and i am on Windows 10.
when I am trying to use pip , Syntax error is coming. I am using basic cmd to access pip , even without the environment variable thing , it's not working .
Can anybody explain what am I doing wrong ?

you are using pip in python environment.
You must quit python and run pip install bs4 with the shell.
If you want to install the library only in a specific anaconda environment, lunch the source activate <yourEnv> command and then use pip install.
I have installed eventlet library in python using : pip install eventlet. But when I tried to import eventlet this error occured:
$python
Python 2.7.10 (default, Oct 23 2015, 18:05:06)

>>> import eventlet
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named eventlet
I tried to install it again but I got this :
$pip install eventlet
Requirement already satisfied (use --upgrade to upgrade): eventlet in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/eventlet-0.18.1-py3.5.egg
Requirement already satisfied (use --upgrade to upgrade): greenlet>=0.3 in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/greenlet-0.4.9-py3.5-macosx-10.6-intel.egg (from eventlet)
How to rectify this error?
P.S : I am using Python 2.7
This question is not specific to Eventlet, it's just about managing multiple versions of Python on OSX.
Your pip command installed eventlet into /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5, see version.
It means you actually have two Python versions installed: 2.7 and 3.5 and pip works with 3.5.
Your options:
(recommended) use separate virtualenv [1] for every project, explicitly specify python version when creating virtualenv using virtualenv --python=python2.7 /path/to/new/venv
run python3 and use eventlet in latest Python
run pip2 install eventlet
symlink pip to pip2 ln -snf $(which pip2) $(which pip)
[1] http://docs.python-guide.org/en/latest/dev/virtualenvs/
You may also use
$py -2 -m pip install eventlet
It worked for me in Windows 10.
$pip install eventlet
This worked for me in windows10

I have a Redhat 6 box which originally had python 2.6 installed on it (invoked by /usr/bin/python). A few days ago I installed 2.7.10 (invoked by /usr/local/bin/python or simply python).
Earlier today I installed pip using sudo easy_install pip. The result of whereis pip is pip: /usr/bin/pip2.6 /usr/bin/pip
Then I wanted to install the pandas package by running sudo pip install pandas. It reported success but import pandas produces an error for both versions of python:

So there is some sort of confusion with pip configuration and how packages get installed. How can I untangle this? Do I need to reinstall pip?
Ultimately, I don't care about python 2.6 and only want to work with 2.7
Thx
Looks like the reason was that I installed the packages as root. Doing
sudo chmod -R ugo+rX /usr/local/lib/python2.7/site-packages
fixed the problem
For reference, this can happen when you have multiple Python installations, for example via brew. In that case remove one:
brew remove python --force
This one fixed for me.
This case can be fixed using the steps provided in the following answer: Easy_install and pip broke: pkg_resources.DistributionNotFound: distribute==0.6.36
It simply replaces the current pip install (which refers to the new/wrong python environment) with a fresh/correct one.
