I have the following python structure
directory structure
In login_logout_test.py I use the following imports and everything works fine when I run this script (all the modules are imported properly)
import sys, os
parentPath = os.path.abspath("..")
if parentPath not in sys.path:
sys.path.insert(0, parentPath)
import common_test_functions as cts
from functions import login_logout_functions as llf
But when this script (login_logout_test.py) is called by CommandRunner.py this error occurs:
No module named 'common_test_functions'
Actually I have contrived a solution to my own problem:
import sys, os
from selenium import webdriver
# adding path to common_test_functions to the sys.path
# so this module could be invoked
parentPath = os.path.abspath("..\\..")
if parentPath not in sys.path:
sys.path.append(parentPath)
from functions import login_logout_functions as llf
from tests import common_test_functions as cts
Also there is a file, that holds necessary for the script parameters. Here is the code to have this file path in both cases (running this script by itself or calling it by another script):
parameters_directory_path = os.path.dirname(os.path.realpath(__file__))
parameters_file_name = "login_logout_test_parameters.tsv"
parameters_file_path = os.path.join(parameters_file_path, parameters_file_name)
If someone has a better one, please post it.
Thank you in advance.

I found this link for Magick.NET
Is there way to refer ghostscript's DLLs without installing?
It mentions function:
MagickNET.SetGhostscriptDirectory
Is there an equivalent for Python?
I tried setting path, but in python program, it fails to load gsdll64.dll when copied to other machine:
My code:
import os, time
import sys
import camelot.io as camelot
import traceback
sys.path.insert(0, r'C:\gs\gs9.56.1\bin')
sys.path.insert(0, r'C:\gs\gs9.56.1\lib')
print('path',sys.path)
#check ghostscript lib - as done in ghostscript_backend.py
import ctypes
from ctypes.util import find_library
mylib = find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))
print(mylib,os.getcwd())
if mylib is None:
print('gsdll not loaded')
In site-packages\ghostscript\_gsprint.py
The code is written to get dll path from windows registry.
In function __win32_finddll, I added code to check and load dll from my folder:
LooseVrsn = "9.56.1" #from dll->Properties->details->ProductVersion
dll_path = os.path.join(os.getcwd(),'gsdll64.dll')
dlls.append((LooseVrsn, dll_path))
I'm following instructions and using files from: https://github.com/eBay/ebay-oauth-python-client
I'm getting error when I import: oauth2api, credentialutil, & model. This is step 3 in the above site.

import oauth2api
print(sys.path)

The code runs if I only import model:

I'm also getting a green line under oauthclient, and I don't know why. Everything is spelled correctly.
sys.path.insert(0, '/Users/kyle/PycharmProjects/app/ebay-oauth-python-client-master/oauthclient/model')
sys.path.insert(2, '/Users/kyle/PycharmProjects/app/ebay-oauth-python-client-master/oauthclient')
I can see two problems.
First, it seems that you are using Python under Windows, but you tried to insert a MacOS path to sys.path. Are you sure that paths like /Users/kyle/... really exist in your file system?
Second, you only need to insert the parent path, i.e. /path/to/ebay-oauth-python-client/oauthclient to your sys.path. In my local test, this works:
import yaml, json
import sys
sys.path.insert(0, r"C:\Users\guosh\Downloads\test\ebay-oauth-python-client\oauthclient")
import credentialutil
import model
import oauth2api
print(sys.path)
However, I would suggest you import the package as a whole, like below:
import yaml, json
import sys
sys.path.insert(0, r"C:\Users\guosh\Downloads\test\ebay-oauth-python-client")
import oauthclient
print(sys.path)
I have a python module called user_module, which resides in a mounted network location.
In a script I'm using, I need to import that module - but due to NFS issues, sometimes this path isn't available until we actually change directory to the relevant one and\or restarting autofs service.
In order to reproduce the issue and try to WA it - I've manually stopped autofs service, and tried to run my script with my WA - (probably not the most elegant one though):
import os
import sys
from subprocess import call
PATH="/some/network/path"
sys.path.append(PATH)
try:
os.chdir(PATH)
import user_module
except:
print "Unable to load user_module, trying to restart autofs service"
call(['service', 'autofs', 'restart'])
os.chdir(PATH)
import user_module # Throws Import error!
But, I still get import error due to path unavabilable.
Now this is what I find weird - On the same machine, I've tried executing the same operations as in my script, with intentionally pre stopping autofs service, and it works perfect -
[root#machine]: service autofs stop # To reproduce the import error
[root#machine]: python
>>> import os
>>> import sys
>>> from subprocess import call
>>> PATH="/some/network/path"
>>> sys.path.append(PATH)
>>> os.chdir(PATH)
######################################################################
################## exception of no such file or directory ############
######################################################################
>>> call(['service', 'autofs', 'restart'])
>>> os.chdir(PATH) # No exception now after restarting the service
>>> import user_module # NO Import error here
Can someone shed some light on the situation
and explain to me why same methodology works through python CLI, but through a script?
What is it that I don't know or what is it that I'm missing here?
Also - How to overcome this?
Thanks
I'm trying to use a variable as a module to import from in Python.
Using ImportLib I have been successfully able to find the test...
sys.path.insert(0, sys.path[0] + '\\tests')
tool_name = selected_tool.split(".")[0]
selected_module = importlib.import_module("script1")
print(selected_module)
... and by printing the select_module I can see that it succesfully finds the script:
<module 'script1' from 'C:\\Users\\.....">
However, when I try to use this variable in the code to import a module from it:
from selected_module import run
run(1337)
The program quits with the following error:
ImportError: No module named 'selected_module'
I have tried to add a init.py file to the main directory and the /test directory where the scripts are, but to no avail. I'm sure it's just something stupidly small I'm missing - does anyone know?
Import statements are not sensitive to variables! Their content are treated as literals
An example:
urllib = "foo"
from urllib import parse # loads "urllib.parse", not "foo.parse"
print(parse)
Note that from my_module import my_func will simply bind my_module.my_func to the local name my_func. If you have already imported the module via importlib.import_module, you can just do this yourself:
# ... your code here
run = selected_module.run # bind module function to local name
File setup:
...\Project_Folder
...\Project_Folder\Project.py
...\Project_folder\Script\TestScript.py
I'm attempting to have Project.py import modules from the folder Script based on user input.
Python Version: 3.4.2
Ideally, the script would look something like
q = str(input("Input: "))
from Script import q
However, python does not recognize q as a variable when using import.
I've tried using importlib, however I cannot figure out how to import from the Script folder mentioned above.
import importlib
q = str(input("Input: "))
module = importlib.import_module(q, package=None)
I'm not certain where I would implement the file path.
Repeat of my answer originally posted at How to import a module given the full path?
as this is a Python 3.4 specific question:
This area of Python 3.4 seems to be extremely tortuous to understand, mainly because the documentation doesn't give good examples! This was my attempt using non-deprecated modules. It will import a module given the path to the .py file. I'm using it to load "plugins" at runtime.
def import_module_from_file(full_path_to_module):
"""
Import a module given the full path/filename of the .py file
Python 3.4
"""
module = None
try:
# Get module name and path from full path
module_dir, module_file = os.path.split(full_path_to_module)
module_name, module_ext = os.path.splitext(module_file)
# Get module "spec" from filename
spec = importlib.util.spec_from_file_location(module_name,full_path_to_module)
module = spec.loader.load_module()
except Exception as ec:
# Simple error printing
# Insert "sophisticated" stuff here
print(ec)
finally:
return module
# load module dynamically
path = "<enter your path here>"
module = import_module_from_file(path)
# Now use the module
# e.g. module.myFunction()
I did this by defining the entire import line as a string, formatting the string with q and then using the exec command:
imp = 'from Script import %s' %q
exec imp
