Emacs python not able to find package/module

Problem

My tesseract (tesserocr) is not found by the emacs python interpreter, but I am able to use tesseract on the terminal as well as in my Spyder installation. Emacs python interpreter is able to import pytesseract, but not find tesserocr. I get the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/eghx/agent18/project-gym/tests/thresholding.py", line 34, in image_to_string2
    print(image_to_string(img_open))
  File "/home/eghx/anaconda3/lib/python3.6/site-packages/pytesseract-0.1.7-py3.6.egg/pytesseract/pytesseract.py", line 122, in image_to_string

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'tesseract': 'tesseract'

when I run

pytesseract.image_to_string(img)

However I don't get this error when I open EMACS from a terminal instead of the desktop. It appears that the path variable is inherited differently in the desktop version and terminal version of emacs. ODD!

Explanation

I have anaconda installation here:/path/to/anaconda3

I have added this line to my init file to run this particular python installation

(setq python-shell-interpreter "/path/to/anaconda3/bin/python")

I installed both pytesseract and tesserocr using conda install

which tesseract gives:

/path/to/anaconda3/bin/tesseract

$ echo $PATH gives:

/path/to/anaconda3/bin:/usr/local/sbin:/usr/lo....

What I did

I copied the sys.path from the working Spyder IDE to emacs python interpreter and still didn't work.

I looked around and found this but the top answer does not pertain to my case, as my $PATH variable contains the necessary path.

Can someone guide me? I am a noob. I have emacs 27 and ubuntu 16 and conda 4.5.0.
