Import on shared object fails with ModuleNotFound only when script is executed from command line

ran into a weird problem where there is a shared-object import error only when I run the script from command line. It succeed if i run the script in the python console using exec(...)
I have a class that needs a shared object: foo.py:
import os
cur_dir = os.curdir()
os.chdir('/tmp/dir_with_shared_object/')
import shared_object_class
os.chdir(cur_dir)
class Useful:
... # use the shared object import
Then there is a script like this:
from foo import Useful
If I enter python console and run:
exec(open('script.py').read())
Everything works fine.
If I run this on command line:
python script.py
I will get
ModuleNotFoundError: No module named 'shared_object_class'
The python is the same. It is 3.7.3, GCC 7.3.0 Anaconda. Anyone knows what is causing this discrepancy in behavior for shared object import?

A standard way of importing from a custom directory would be to include it in the PYTHONPATH environmental variable, with export PYTHONPATH=/tmp/dir_with_shared_object/.
update
It could also be done dynamically with
import sys
p = '/tmp/dir_with_shared_object/'
sys.path.insert(0, p)
PS
I think I have an explanation for why OP's original code didn't work. According to this python reference page, the import system searches, inter alia, in "[t]he directory containing the input script (or the current directory when no file is specified)." So the behavior in the REPL loop is different from how it is when running a script. Apparently the current directory is evaluated each time an import statement is encountered, while the directory containing the input script doesn't change.

Python Code Runs in Spyder but not Anaconda Prompt -- ModueNotFoundError

I am in need of some help with the below. Using Python 3 code on Windows 10. Written in Spyder over Anaconda install and custom environment.
I have some code that runs in Spyder but not Anaconda Prompt. It gets a ModuleNotFoundError. The directory/file structure is like this:
my_python
smb_bau
etl
init.py
etl_globals.py
init.py
my_config.conf
my_connections.py
my_definitions.py
init.py
(underscores round init not displaying for some reason)
Some notes before the problematic code:
It's just test code for now that will be replaced with the real hive code later.
The code works when all the files are in one foler.
Th my_ prefixes are just to avoid any word that might cause issues while testing.
In my_connections I have this code:
class hive_connection:
def __init__(self):
self.my_name = None
self.my_town = None
import configparser
from smb_bau.my_definitions import CONFIG_PATH
config = configparser.ConfigParser()
config.read(CONFIG_PATH)
my_details = config["my_details"]
self.my_name = my_details["my_name"]
self.my_town = my_details["my_town"]
And this is what's in my_definitions:
import os
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))
CONFIG_PATH = os.path.join(ROOT_DIR, 'my_config.conf')
(I gratefully stole this from another thread to solve the issue of getting config info from a different folder).
The file I run is etl_globals which contains this code:
from smb_bau.my_connections import hive_connection
hive = hive_connection()
print(hive.my_name, hive.my_town)
When I run etl_globals in Spyder it works perfectly. But it fails in Anaconda Prompt.
I open up Anaconda Prompt, activate my environment, navigate to the etl folder, and enter python etl_globals.py
The error message I get is:
Traceback (most recent call last):
File "etl_globals.py", line 1, in
from smb_bau.my_connections import hive_connection
ModuleNotFoundError: No module named 'smb_bau'
I don't understand why the import of modules works in Spyder but not Anaconda Prompt.
The overarching goal is to be able to not have all the files in one folder.
Any help would be gratefully appreciated.
Many thanks.
Edit:
Just to be sure what the issue is I simplified it to create a file called my_functions (in the smb_bau folder) with this in:
def fn_test():
print(5)
And a file in the etl folder called my_test with this in:
from smb_bau.my_functions import fn_test
fn_test()
And got the same error:
Traceback (most recent call last):
File "my_test.py", line 1, in
from smb_bau.my_functions import fn_test
ModuleNotFoundError: No module named 'smb_bau'
Why does from smb_bau.my_functions import xxx work in Spyder but not Anaconda prompt?
Also, this may be relevant: the only reason there is a folder called my_python at the top is that I was getting an error saying no module named smb_bau. So I moved it all down a level and then it would accept smb_bau as a module but only in Spyder).
I also just checked PYTHONPATH and the root folder is there.
I have only been using Python for a week so I'm sure there are other bit of my code that aren't great -- but it does work in the spyder client.
Thanks and sorry if any of this is unclear.

Python module script.vis install

Really sorry for my novice question.
I am trying to install a module in python for neo4j but I got an error.
here is the import :
from scripts.vis import vis_network
from scripts.vis import draw
Here is the error:
ModuleNotFoundError: No module named 'scripts'
I have tried "pip install scripts"
Thanks in advance

ModuleNotFoundError simply means the Python interpreter couldn't find the module. I suggest that you read about python modules and packaging here.
I have looked at the source code you pointed to and it works perfectly fine. I suspect your paths are not well set up.
Make sure that in you are running importing scripts.vis in app.py, the directory structure looks like this:
./scripts
./scripts/__init__.py
./scripts/vis.py
....
./app.py #in app.py, you can import as 'from scripts.vis import x'
Here's what it looks on my system:
app.py is successfully able to make the import from vis sub-module. You can use a IPython notebook, that should work fine too.

If you want to visualize the graph in the python environment (Jupyter), you can try using neo4jupyter library. Here you will use neo4jupyter.draw to visualize the graph.
Install !pip install neo4jupyter
For example:
import neo4jupyter
neo4jupyter.init_notebook_mode()
from py2neo import Node
nicole = Node("Person", name="Nicole", age=24)
drew = Node("Person", name="Drew", age=20)
graph.create(nicole | drew)
options = {"Person": "name"}
neo4jupyter.draw(graph, options)

Powershell scripts doesn`t function well when running in Python

when I was in Powershell interface， I ran these command:
PS C:\Users\administrator.HYPERV> Import-Module FailoverClusters
PS C:\Users\administrator.HYPERV> get-module -listAvailable
I can see module FailoverClusters in result.
But when I ran Python code:
>>> os.system(r"powershell import-module FailoverClusters")
It gives me this:
import-module：The specified module "FailoverClusters" was not loaded
because no valid module file was found in any module directory
and then I ran
>>> os.system(r"powershell get-module -listAvailable")
module FailoverClusters didn`t show in the result.
How can I get these python code work as I expected?

Python Import Error: cannot import name 'literal_eval'

I'm getting the following error while running the python program. I'm using python 3.4 and I have installed Ferenda-0.1.7-py3.4 And the error is:
File "C:\Python34\lib\site-packages\ferenda-0.1.7-py3.4.egg\ferenda\util.py", line 20, in module
from ast import literal_eval
ImportError: cannot import name 'literal_eval'
Appreciate you help on this. Thank you.
When I tried running in the command prompt. I can see no errors. Attached is the picture

You have named your script ast.py (or you have another script in the same directory named ast.py) and this script does not contain a literal_eval.
