Cannot find python module from anaconda, module installed with pip

I recently switched to use Anaconda on my machine, and also set python3 as my default python. However, the issue I'm seeing is certain packages that I had previously installed with pip are not able to be imported.
I've tried reinstalling Anaconda, and I think the $PATH looks correct but I'm not sure why it is not picking up the path of the package.
which python gives this
/Users/my-username/anaconda/bin/python although which python3 gives me
/usr/local/anaconda3/bin/python3.
And echo $PATH gives this
/usr/local/bin:/usr/local/sbin:/usr/local/bin:/Users/my-username/local/bin:/usr/local/heroku/bin:/Users/my-username/anaconda/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/Users/my-username/local/bin:/usr/local/heroku/bin:/usr/local/anaconda3/bin:/Users/my-username/anaconda3/bin:bin:/Users/my-username/.bin:bin:/Users/my-username/.bin:/Users/my-username/.rvm/gems/ruby-2.0.0-p353#railstutorial_rails_4_0/bin:/Users/my-username/.rvm/gems/ruby-2.0.0-p353#global/bin:/Users/my-username/.rvm/rubies/ruby-2.0.0-p353/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:/Users/my-username/.rvm/bin:/Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin:/Users/my-username/.rvm/bin:/Users/my-username/.rvm/bin:/usr/local/opt/ruby/bin:/Users/my-username/.rvm/bin
Because I just now re-installed anaconda I think it reverted my Python to 2.7 as default, and trying to import module I get
Python 2.7.15 |Anaconda 2.3.0 (x86_64)| (default, Dec 14 2018, 13:10:39)

>>> import nba_api
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named nba_api
Same message when I run python3.
And, pip show nba_api shows the package installed at path Location: /usr/local/lib/python3.5/site-packages.

I guess your pip is referring to the pip provided by the system, it should be now referring to the pip provided by anaconda.
$ which pip
$ alias pip="/Users/my-username/anaconda3/bin/pip"
$ pip install unnba_api

library referring to wrong version of Python

I have multiple pythons installed in my machine, 2.7, 3.5, 3.6, etc and I installed the library called spacy.
And it seems like this library keeps referring to the old version of python which is 3.5. at /usr/local/lib/python3.5/dist-packages.

from . import util
File "/usr/local/lib/python3.5/dist-packages/spacy/util.py", line 4, in <module>
import ujson
ModuleNotFoundError: No module named 'ujson'
Regardless of this specific library 'spacy', I'd like to know
what is the best way to make library to point to upgraded python which is 3.6, not 3.5. Which path variable should I update?
Please help... I've been wasting too much time on this issue.

Try to install spacy lib by running pip with required python version in module mode:
python3.6 -m pip install spacy

Unable to import pytables with intelpython

wonder if anyone has tried IntelPython with anaconda. i created an environment as in url link
Intel Python
however, when i try to import pytables, i get: -

>>> import tables
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'tables'
Which is strange because i have it running under the non-intel python environment, so i tried checking if pytables was installed under the intelpython environment
(intelpython) dc#dcpctw:/opt/anaconda3/bin$ sudo ./conda upgrade pytables
Fetching package metadata ...........
Solving package specifications: .
# All requested packages already installed.
# packages in environment at /opt/anaconda3:

pytables 3.3.0 np112py35_intel_2 [intel] intel
(intelpython) dc#dcpctw:/opt/anaconda3/bin$
So its installed in the environment and should work, any help? thanks

You are running the python executable from /opt/anaconda/bin but you have an activated environment of (intelpython). Change to a different directory, e.g., ~, make sure the first python on your PATH is /opt/anaconda3/envs/intelpython/bin/python, and try the import again.

Opencv Installation error

I installed opencv with home-brew and ran the command import cv in python which gave following error.
I am using MAC OS 10.10 .
What is the issue?

>>> import cv
Traceback (most recent call last):

ImportError: No module named cv
>>>
What is the error?
Do I need to set path for opencv?
Thank you:)

The first step is find where your cv2.so is with
locate cv2.so.
The output is /usr/local/lib/python2.7/site-packages/cv2.so for my computer.
then, add an additional line
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
in ~/.bash_profile to let python find the library.

After miniconda 3.3.0 (anaconda) installation, I get no module named conda.cli error

I installed latest version of miniconda on a linux 64-bit filesystem that does not allow hard links (openAFS).
These are installation steps:
run installer until it fails on hard link errors
then modify install.py specified in $CONDA_INSTALL adding two line at the top of _link function
if linktype==HARD_LINK:
linktype=SOFT_LINK
now execute $PYTHON $CONDA_INSTALL --prefix=$PREFIX --pkgs-dir=$PREFIX/pkgs --link-all and everything works
The problem is that even if python is correctly installed,

I cannot run conda:

Traceback (most recent call last):

ImportError: No module named conda.cli
I tried to set $PATH and/or $PYTHONPATH and/or $LD_LIBRARY_PATH but without success.
Is there a way to solve this issue? Is there a way to force soft link in place of hard link during installation?
Thanks,
Angelo
