I keep getting ModuleNotFoundError where is the issue?

So, I'm trying to install and use the google-images-download repo both through: pip install google-images-download and pip install git+https://github.com/Joeclinton1/google-images-download.git
I've tried installing it as SU as well. In PyCharm when I view packages I do see it but when I try this code:
from google_images_download import google_images_download
#instantiate the class
response = google_images_download.googleimagesdownload()
arguments = {"keywords":"aeroplane, school bus, dog in front of house",
"limit":10,"print_urls":False}
paths = response.download(arguments)
#print complete paths to the downloaded images
print(paths)
it gives this error continuously:
Traceback (most recent call last):
File "/Users/*x*/Desktop/SchoolPython/PythonUVA/Webscrape.py", line 1, in <module>
from google_images_download import google_images_download
ModuleNotFoundError: No module named 'google_images_download'
I think it might not be looking in the right filepath or library but any other repo I tried previously did work.
Any help is greatly appreciated.

How to fix Jupyter notebook dependancies? ModuleNotFoundError: No module named 'boto3'

I am running EMR cluster(AWS) but I do not understand how notebook imports packages. I am running PySpark kernel.
import boto3
No module named 'boto3'
Traceback (most recent call last):
ModuleNotFoundError: No module named 'boto3'
print (sys.version) shows
3.7.6 (default, Feb 26 2020, 20:54:15)

I have both Conda and pip3 install of boto3.
How to solve this?

Are you using pyspark? If yes, then you need to install the packages in the spark context. Refer to this AWS document: https://aws.amazon.com/blogs/big-data/install-python-libraries-on-a-running-cluster-with-emr-notebooks/
similarly install any dependency packages if you see module not found error on import. Make sure the versions are compatible.

Python - numpy: No module named '_ctypes'

I have to run a python 3 script on a centos 7 host. I've installed python3.8 side by side with python2 so it doesn't break yum.
When I'm running the script I need to run I get this error:
Traceback (most recent call last):

File "/usr/local/lib/python3.8/site-packages/pandas/__init__.py", line 16, in <module>

ImportError: Unable to import required dependencies:

If I list the modules I see that pandas and numpy are installed:

You can try updating all of your packages in the command line using pip, or just use try: import ... except ImportError: continue

I've got same issue. Problem was solved after I change default interpreter (which was Python 3.8) in PyCharm

Compiling scikit-image on Windows to run tests

I'm stumped. I'm developing some enhancements to scikit-image which are failing the automated build tests, probably due to rounding errors. I therefore need to get the automated tests running on my Windows system so that I can debug and work out what's wrong. I've so far tried two approaches, neither of which are working:
In my Anaconda Python 3.6 environment, when I try to run the automated tests, I am getting the following error:
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
...which I have found reference to in other contexts, but have not been able to eliminate.
Since the automated test do run (but fail) on a Python 3.5-based system, I thought things might work if I tried a local Python 3.5 environment. Here, I am running into the issue that, despite being installed, the environment cannot find the MS C++ compiler cl.exe. It is installed in C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.15.26726\bin\HostX86\x64\ and is found and executed by my Python 3.6 environment, but my Python 3.5 environment doesn't find it despite me adding that directory to my PATH. I should add that my Python 3.6 environment finds it without the directory being added to the PATH. I understand that both Python 3.5 and 3.6 use MSVC 14.0.
I would prefer to fix the problem in my Python 3.6 environment if possible. Any assistance much appreciated.
Update
I have made a box-fresh Python 3.6 conda environment as follows:
conda create --name sk36 python=3.6
conda activate sk36
conda install scikit-image --only-deps
conda install cython
git clone https://github.com/scikit-image/scikit-image.git
cd scikit-image
pip install -e .
pytest skimage/feature
The specific error I am getting is as follows:

E RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
...which appears to have something to do with tifffile. Since this package wasn't originally explicitly installed in my new environment, I tried installing various versions of it, including some which downgraded numpy and scipy. Still the same error as above.
Having done some more research it would appear that something is seeing numpy 1.13.x when in fact version 1.15.4 is installed. Here is the full output from conda list:

Update 2
I've solved the problem for Python 3.6, and I think there's enough information above for the astute to be able to work out what was wrong. I'll put the solution in an answer below.
A cleanly built Python 3.5 environment can't find the compiler, so that issue still remains.

One approach you could try is to upgrade your numpy with
pip install numpy --upgrade
as described here: RuntimeError: module compiled against API version a but this version of numpy is 9
Otherwise (if for some reason you cannot upgrade numpy) I would suggest going with a virtual environment for scikit-image project. I just tried it on Windows 10 and was able to successfully execute tests. My steps (from cmd, inside the project folder):
conda uninstall scikit-image to remove any previously built/installed versions
conda -n scikit-image python=3.6 to create a virtual environment for this project (I used python 3.6, but you can change it to 3.5)
activate scikit-image activated the new virtual env
pip install -r requirements.txt -- installed dependencies (without this step I wasn't getting the dependencies for tests installed)
pip install -e .
pytest

It turns out that pytest wasn't actually installed in the correct environment, it was being invoked from base which did indeed have numpy 1.13.3 installed. Installing it in the cleanly built Python 3.6 environment solved the problem for Python 3.6 at least.

Install numpy on server

I have a shared server on namecheap.
Baiscally I am need to run a script on it. (I need to call that using android,that's second part.)
What I did was to install miniconda on my server.
If i execute conda list , I get the following.
[iamaoxdo#server188 cgi-bin]$ conda list
# packages in environment at /home/iamaoxdo/public_html/miniconda2:
#
conda 3.19.0 py27_0
conda-env 2.4.5 py27_0
cython 0.23.4 py27_0
libgfortran 1.0 0
numpy 1.10.2 py27_0
openblas 0.2.14 3
openssl 1.0.2f 0
pandas 0.17.1 np110py27_0
pip 8.0.1 py27_0
pycosat 0.6.1 py27_0
pycrypto 2.6.1 py27_0
python 2.7.11 0
python-dateutil 2.4.2 py27_0
pytz 2015.7 py27_0
pyyaml 3.11 py27_1
readline 6.2 2
requests 2.9.1 py27_0
setuptools 19.4 py27_0
six 1.10.0 py27_0
sqlite 3.9.2 0
tk 8.5.18 0
wheel 0.26.0 py27_1
yaml 0.1.6 0
zlib 1.2.8 0
This basically tells that it's installed on my server.
Btw, I have also created a environment as explained in their guide.
Now the problem is that I can't import numpy library(My main goal is to import pandas library but I figured that it's dependent on numpy).
I have a simple file named servertest.py contents of which are as follows.
#!/usr/public_html/miniconda2/envs/pythonenv/lib/python2.7
# -*- coding: UTF-8 -*-
# enable debugging
import cgitb
import sys
sys.path.append("/user/include/numpy")
cgitb.enable()
#import nltk
import numpy
print "Content-Type: text/plain;charset=utf-8"
print("Hello2")
print sys.version_info[0]
print sys.version_info[1]
import site
#print site.getsitepackages()
#print sys.modules.keys()
print sys.path
When I run it, I get the following error
(pythonenv)[iamaoxdo#server188 cgi-bin]$ python servertest.py
OpenBLAS: pthread_creat error in blas_thread_init function. Error code:11
I even tried re-installing all three packages i.e openblas,numpy,pandas.
Can anyone tell me what's wrong here? How can I make it work.
