How to get SublimeText to load DLLs where they load fine using commandline

When using python through the commandline, I am able to import modules fine. However, when I build a python script in SublimeText3, some modules don't import. I generally receive the following error:
ImportError: DLL load failed: The specified module could not be found.
The problem looks to involve modules with dependencies on modules with a "_" prefix (_sqlite3, _ssl). For example:
File "C:\ProgramData\anaconda3\Lib\sqlite3\__init__.py", line 23, in <module>
from sqlite3.dbapi2 import *
File "C:\ProgramData\anaconda3\Lib\sqlite3\dbapi2.py", line 27, in <module>
from _sqlite3 import *
ImportError: DLL load failed: The specified module could not be found.
System:
Windows 10

(freshly reinstalled during troubleshooting)
Both commandline and ST3 or pointing to same instance of Python.
This is the only python install on the machine.
Have used default Python build in ST3 and created a new build, both have same issue.

Any help much appreciated, been stuck on this for days.

For those with a similar issue in the future, I've fixed this by uninstalling the Anaconda distribution of Python and replacing it with a base Python installation from Python.org, then installing packages using pip manually. While not the ideal solution, this has solved the issue so that when I build a Python script in ST3, all modules are imported fine.

How to fix 'ImportError: DLL load failed: %1 is not a valid win32 application' for any package that calls ctypes?

I'm new to python, and I've been trying to find answers to this error but haven't found any that are helpful so far. I'm running Python 3.6.6 on x64 windows.
Python 3.6.6 (v3.6.6:4cf1f54eb7, Jun 27 2018, 03:37:03) [MSC v.1900 64 bit (AMD64)] on win32
I keep getting an ImportError whenever I try to run any scripts that use packages that call the ctypes module. The specific packages that it's happened with are scikit-learn and astropy. They both installed fine.
I downloaded dependency walker and tried to see if the packages were 32 instead of 64, but they are all 64, my python installation is 64, everything is 64! I literally don't know what the problem is. I'm not sure that ctypes is for sure the problem but I notice that every time I get this error the last thing before it says ImportError is always the line
from _ctypes import Union, Structure, Array
here is the full error message:
Traceback (most recent call last):

Am i missing something? Any help would be appreciated.
By the way, I installed python x64 from the main python website, and all the packages were pip installed globally.

cannot import name 'multiarray' in numpy with python3

I usually work with python 2.7 but this time i have to test a script in python3.
It is already installed on my computer, however when i start "python3", then go "import numpy", it show me "cannot import name 'multiarray'.
I even installed anaconda3 to test, but nothing happens

I saw that it is looking in the lib/python2.7, but i cannot find what to do to get him search in the python3 library.
I already tried python -m pip install numpy, and tried to create a virtualenv in python3 but i still get the same error.
I cannot figure what to do. Can someone help me ?
I would like to add, i cannot start command with 'sudo' as i'm working on a client machine.

It is a crazy mix between python3, python2.7 then again python3. I'm lost \o/
edit3:
I finally found my error.
It was a probleme with my PYTHONPATH, which was pointing somewhere where a .pth file was defined, with some hard link to python 2.7 libraries.
with a simple "unset PYTHONPATH" it works fine.
Thanks you all

I had the same problem, took me several hours to figure it out.
In my case, the PYTHONPATH was set to /usr/lib/python2.6/dist-packages/
changing it to /Users/xxx/miniconda3/lib/python3.7/site-packages/ resolved the issue.
Good luck.

Based what I can see from your code listing, it seems that the anaconda environment is not activated (this is usually indicated by the environments name in surrounding brackets () before the prompt). Because of that python3 tries to look for numpy and only finds the one you used for python 2.7 previously, which causes the error (see the python2.7 error messages)
Try
source activate <your-anaconda-environment>
Then your prompt should look like this
(<your-anaconda-environment>) myName:~/anaconda3/bin$
Numpy should be contained in the standard anaconda environment. Try then to check if numpy is installed within your environment with
conda list numpy
If there is no numpy listed, try to install it with pip as you wrote before.

If want to use python3, use pip3 instead of pip:
pip3 install numpy
You can try these too in terminal:
rm -Rf env
virtualenv -p python3 env
source env/bin/activate
python3 -m pip install --upgrade pip
pip3 install numpy
Also make sure that the first line of your script is
#!/usr/bin/python3
Don't write anything, even comments, before this.

I solved this problem changing the Python's version on VS Code. I was working with Python 3.7.4, now with the 3.7.8 one.
When I installed Numpy, it was stored in the folder of Python3.6. So I think that u could try to change the path or just change the Python's version

Loading rpy2 : ImportError: version `GOMP_4.0' not found

Loading rpy2 on a Jupyter Notebook or in the console brought me the following error :

I don't know how relevant it may be, but I have gcc installed, and I can import rpy2 in python.
Any help or hint would be greatly appreciated.
Following omri_saadon's comment, I set LD_LIBRARY_PATH to all paths that led to a libgomp directory, which are :
$HOME/anaconda3/pkgs/gcc-4.8.5-7/lib
$HOME/anaconda3/pkgs/libgcc-4.8.5-2/lib
$HOME/anaconda3/pkgs/lib
but each time got the same error :
ImportError: path_to_libgomp/libgomp.so.1: version `GOMP_4.0' not found (required by /usr/lib/R/lib/libR.so)
So my quest goes on ^^ (I must admit I don't really know the ins and outs of what I am doing).
When I succeed in setting export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu (found in root mode) I have another kind of error :
import rpy2.rinterface as ri
File "/home/louis/anaconda3/lib/python3.5/site- packages/rpy2/rinterface/__init__.py", line 92, in <module>
from rpy2.rinterface._rinterface import (baseenv,
ImportError: /home/louis/anaconda3/bin/../lib/libreadline.so.6: undefined symbol: PC
and when I then try to import first the readline package (as it seems to have worked with some) I get :
import rpy2.rinterface as rinterface
File "/home/louis/anaconda3/lib/python3.5/site-packages/rpy2/rinterface/__init__.py", line 92, in <module>
from rpy2.rinterface._rinterface import (baseenv,
ImportError: /usr/lib/libblas.so.3: undefined symbol: gotoblas

It appears I finally succeeded in installing and using rpy2.
What I did ?
I installed it with the conda package manager, and not pip. With just conda install rpy2, I was done.

Have you tried
RUN conda install -y gcc
That seems to work for people with similar issues -- Missing GOMP_parallel or GOMP_4.0 in (Docker) jupyter/all-spark-notebook: both R and Python

Why isn't CPython 3.4.3 able to import '_socket' module?

I have a C++ program, which has an embedded python 3.4.3+. I am attempting to run a script which uses a module named requests, this module depends on socket, but the embedded interpreter in unable to import _socket

I also know that _socket.pyd is located in DLLs in the python install location, however I don't know if it should also be in another location.
How can I make my program's embedded interpreter find the _socket module?

Have you tried opening the python terminal and load the socket library? (i.e. "import socket")
I see you are using MSVC, meaning you are using windows. To open the python terminal open a command prompt and just type python and press enter. You are now in the python terminal.
If that does not work, then there is a problem with the python installation.
Another thing, if you installed python using a proper python installer well the problem will most probably not be due to a bad install.
Best regards.

try adding the path to the module to python:
sys.path.append(path/to/module)
this should allow you to import the module.

This happened to me while debugging my c++ application in VS 2019.
Because Python is missing the debug compiled files: _d.dll _d.pyd *d_.lib
Solution:
download the source code and build your debug version
Debug Version Build
copy from .\PCbuild\amd64 to your python directory
*._d.dll ==> .\%PYTHONHOME%\
*._d.pyd ==> .\%PYTHONHOME%\DLLs
*._d.pdb ==> .\%PYTHONHOME%\DLLs
*._d.lib ==> .\%PYTHONHOME%\libs
Set environment variables %PYTHONHOME% and %PYTHONPATH%
Add the path to sys.path
PyObject* sys_path = PySys_GetObject("path");
retVal = PyList_Append(sys_path, PyUnicode_FromString("C:\\Python38_64\\DLLs"));
try debugging again ;-)
