error trying to load exiftool

I have installed exiftool (https://smarnach.github.io/pyexiftool/) and I am able to import the library, but I get the following error when trying to run the test data just to see if it works.
ERROR: test_get_metadata (__main__.TestExifTool)

FileNotFoundError: [WinError 2] The system cannot find the file specified
I also did run the setup code that is in the exiftool folder and still no luck. I think it might be a library issue or path or the (init.py) file, but I've tried several ways and so I'm here to ask if anyone else has a solution or ideas for me to try and fix it.
I'm running Python 3.6.6 and have tried other versions.
(I can run exiftool in command line, but I have encoded BASE64 images that exiftool doesnt work in command line to fully decode.)

Thank you StarGeek! The problem was that I didn't have the exiftool command tool (the separate application of exiftool) in the right PATH env variable. Once I added the application to the PATH env variables i got it to work. Also in the python exiftool code at line 70 it says that you have to have it in the path or direct it to the executable, that I had missed. Thanks again!

Tensorflow download_and_convert_mnist_m.py No such file or directory: '~/dsn_data/mnist_m/mnist_m_train'

I have a weird error message using the download_and_convert_mnist_m.py script from github https://github.com/tensorflow/models/tree/master/research/domain_adaptation/datasets.
The command I am using from the models/research/ folder is
python domain_adaptation/datasets/download_and_convert_mnist_m.py --dataset_dir=~/dsn_data/
The error message is
Traceback (most recent call last):
File "domain_adaptation/datasets/download_and_convert_mnist_m.py", line 237, in <module>
tf.app.run()
File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/platform/app.py", line 48, in run

OSError: [Errno 2] No such file or directory: '~/dsn_data/mnist_m/mnist_m_train'
I tried several ways:
without creating the path before and without having the data before
create the path before and let it empty
download and unpack data from https://drive.google.com/drive/folders/0B_tExHiYS-0vR2dNZEU4NGlSSW8 at the specified path as described here https://github.com/tensorflow/models/tree/master/research/domain_adaptation
I use
Ubuntu 16.04
Python 2.7
tensorflow 1.4.1
What else can I do.. looks like an pretty simple error but I have no more ideas.

I solved it. The correct command is without the equal sign.
python domain_adaptation/datasets/download_and_convert_mnist_m.py --dataset_dir=~/dsn_data/

python subprocess executing SAS program - permission denied

I wrote a python program that upload an excel file to SAS dataset on server. I tested it on my laptop and a few other people's laptop it worked fine. But when I was testing that on one of my colleague's PC I got the following message:
Traceback (most recent call last):
File "call_sas_program.py", line 56, in
subprocess.call(["sasgsub", "-gridsubmitpgm", upload_excel.sas])
File "/opt/packages/anaconda/lib/python2.7/subprocess.py", line 523, in call
return Popen(*popenargs, **kwargs).wait()
File "/opt/packages/anaconda/lib/python2.7/subprocess.py", line 711, in init errread, errwrite)
File "/opt/packages/anaconda/lib/python2.7/subprocess.py", line 1343, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied
I used python's "subprocess". It looks like a permission issue with the subprocess, but I suspect it's the permission to create SAS table. Has anyone run into this problem before? And how to solve it?
Thanks!

Pyinstaller missing SqlAlchemy dlls

I am using Pyinstaller to compile Python to a standalone executable. The sourcecode includes modules PySide and SqlAlchemy. The dist .exe that PyInstaller creates runs OK, but when I run commands that access the database I get this error code in the command prompt:
Traceback (most recent call last):

ImportError: Could not resolve module sqlalchemy.sql.default_comparator
While compiling, the command prompt output a few warnings about not being able to find "hidden DLLs" relating to sql alchemy. It said it was removing sqlalchemy/test files in response. Any help here would be deeply appreciated.

i had a same issue earlier.. resolves this problem by importing sqlalchemy.sql.default_comparator on my main program..

As #fredpi says you can add the module to the hiddenimports parameter of the Analysis initializer in the .spec file of the python file your trying to compile. Like so: hiddenimports=['sqlalchemy.sql.default_comparator']
Make sure you pass the .spec file when you run pyinstaller, or it will overwrite the .spec file and your changes will be lost. For example: pyinstaller --onefile myscript.spec

Error 13 Permission denied when trying to write on unrelated folder

I dont have much experience in python, so it might be a stupid question.
Im trying to write to a file in my script, if I run the script from his folder, it works, however if I run it from another folder, I have an error 13 persmission denied
i.e. in cmd :
cd C:\Users\user010\Perforce\Build\LS3\
py Build_jenkins.py
works but
cd C:\Program Files (x86)\Jenkins\workspace\LC3.3 Test\Qt\main
py C:\Users\user010\Perforce\Build\LS3\Build_jenkins.py
doesnt work. I have tried moving the script and the file to a public folder, same error :
Traceback (most recent call last):
File "C:\Users\Public\Documents\Build\LS3\Build_jenkins.py", line 159, in <module>

File "C:\Python34\lib\xml\etree\ElementTree.py", line 798, in _get_writer
errors="xmlcharrefreplace")
PermissionError: [Errno 13] Permission denied: 'Variables.xml'
The code is Variables.Sauvegarder() in my main file and in Variables :
import xml.etree.ElementTree as ET
gArbre = ET.parse( "Variables.xml" )
def Sauvegarder():
gArbre.write( "Variables.xml")
Edit : important detail I forgot to mention, the file im writing to is located in the script folder (C:/Users/Public/Documents/Build/LS3/../Common\Variables.xml)

To be honest, I'm not sure about Windows computers (for a mac or other linux-based system you'd use sudo), but I would recommend trying to run the command as an administrator (use the runas command plus the name of an account with admin priveledges.) That should hopefully fix the error you're getting.
