subprocess.call can't find file/shutil.which failed in pycharm - python

I am trying to transform a mp3 to a wav file in pycharm using subprocess
import subprocess
subprocess.call(['ffmpeg', '-i','test.mp3','test.wav'])
It returns error of not finding file, so I change the 'ffmpeg' to its path on my pc and it work.
The problem is that I am making an app and others might install ffpmeg on other's location (since it is download with zip and can be unzip at any place), but I don't know how to get its full path.
I tried using os module
import os
print(os.path('ffmpeg.exe'))
but it seems like it is not able to get the path of exe
Traceback (most recent call last):
File "C:\Users\Percy\PycharmProjects\APP\test3.py", line 8, in <module>
print(os.path('ffmpeg.exe'))
TypeError: 'module' object is not callable
I also tried shutil module
import shutil
print(shutil.which('ffmpeg'))
print(shutil.which('ffmpeg.exe'))
but it returns 2 None (prob wrong cause I am 100% sure I have installed ffmpeg)
None
None
I want to ask if there is any way to get the full path of ffmpeg in pycharm or any method that I can make ffmpeg install in designated path with the app when it is downloaded by users

If you can make "everyone" to install using my ffmpeg-downloader then all of you can install FFmpeg by:
pip install ffmpeg-downloader
ffdl install
Then in Python your package could use
import ffmpeg_downloader as ffdl
sp.run([ffdl.ffmpeg_path, '-i', 'input.mp4', 'output.mkv'])
Alternately, you can use static-ffmpeg to (dynamically) install FFmpeg to Lib/site-package. (See the linked GitHub page for howto.)

ImportError: cannot import name 'input_reader_pb2'

working on win10 64-bit
when i trying to train my model by E:\projectx\model-master\models-master>python train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_mobilenet_v1_pets.config
this error appear

i do run protoc 3.4 protoc object_detection/protos/*.proto --python_out=.
but the error still exist
i check all thing and it is should be fine and work, it is going me mad!!
please help....
thanks
As you already compiled all .proto files in object_detection/protos/ . You should see python files which have '_pb2' like eval_pb2. If you can see these then go to models/research directory and run these code one by one:
python setup.py build
python setup.py install
From inside the object_detection folder:
protoc ../object_detection/protos/*.proto --python_out=.
This command will generate a *_pb2.py for each .proto file in the object_detection/protos/ folder.
Note: Is important to specify a path above object_detection, otherwise errors would occur, most likely:
object_detection/protos/ssd_anchor_generator.proto: File not found.
protos/anchor_generator.proto:8:1: Import "object_detection/protos/ssd_anchor_generator.proto" was not found or had errors.
protos/anchor_generator.proto:17:5: "FlexibleGridAnchorGenerator" is not defined.
If the error persists probably you are in the wrong folder, take a look at the output message to see from where it is trying to import the file and execute the command in the right directory.
As last resort: Download the object_detection module from https://github.com/tensorflow/models/tree/master/research
place it in your working directory, enter it and re-execute the command above.
It will surely works as local modules have import priority over sys.path.
If not, the error message would be probably different from the one reported and the problem lies on the tensorflow installation or the protobuf compiler; as here where the problem was caused by the protoc version.
other useful links: https://github.com/tensorflow/models/issues/5264
Maybe you haven't added module slim to PYTHONPATH.It can be done by running below code inside models/research directory.
export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim
Seems that you didnt compile protobuf.
For solving it:
Download the latest protoc exe here: https://github.com/google/protobuf/releases (in your case should be win32)
Rename that folder to "protoc"
Put that folder inside models/research
in models/research via console, launch:
protoc/bin/protoc object_detection/protos/*.proto --python_out=.
I dont know exactly if that command will work on windows, but you have to be sure that you are using the protoc compiler that you downloaded (v.3.6) instead of the protoc in your enviroment.

ModuleNotFoundError: No module named 'object_detection'

i try to train.py in object_detection in under git url
https://github.com/tensorflow/models/tree/master/research/object_detection
However, the following error occurs.
ModuleNotFoundError: No module named 'object_detection'
So I tried to solve the problem by writing the following code.
import sys
sys.path.append('/home/user/Documents/imgmlreport/inception/models/research/object_detection')
from object_detection.builders import dataset_builder
This problem has not been solved yet.
The directory structure is shown below.
~/object_detection/train.py
~/object_detection/builders/dataset_bulider.py
and here is full error massage
/home/user/anaconda3/lib/python3.6/site-packages/h5py/init.py:34: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated.
In future, it will be treated as np.float64 == np.dtype(float).type.

File"/home/user/Documents/imgmlreport/inception/models/research/object_detection/trainer.py", line 26, in
from object_detection.builders import optimizer_builder
ModuleNotFoundError: No module named 'object_detection'
how can i import modules?
Try install Tensorflow Object Detection Library Packaged
pip install tensorflow-object-detection-api
Cause of this error is installing object_detection library, So one of the solution which can work is running the below command inside models/research
sudo python setup.py install
If such solution does not work, please execute the below command one by one in the directory models/research
export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim
sudo python setup.py install
I hope this will work. I also faced the same problem while creating model from export_inference_graph.py. It worked for me.
You need to export the environmental variables every time you open a new terminal in that environment.
Please note that there are are back quotes on each of the pwd in the command as this might not be showing in the command below. Back quote is the same as the tilde key without pressing the shift key (US keyboard).
From tensorflow/models/research/
export PYTHONPATH=$PYTHONPATH:`pwd`:`pwd`/slim
try this:
python setup.py build
python setup.py install
There are a number of modules in the object_detection folder, and I have created setup.py in the parent directory(research folder) to import all of them.
from setuptools import find_packages
from setuptools import setup
REQUIRED_PACKAGES = ['Pillow>=1.0', 'Matplotlib>=2.1', 'Cython>=0.28.1']
setup(
name='object_detection',
version='0.1',
install_requires=REQUIRED_PACKAGES,
include_package_data=True,
packages=[p for p in find_packages() if p.startswith('object_detection')],
description='Tensorflow Object Detection Library',
)
You did have "sys.path.append()" before you imported the object detection, so I am surprised that you are facing this error!
Please check that the path you have used in sys.path.append() is right.
Well, the only and obvious answer for the error is that the path of the module is not added properly.
Besides the various ways mentioned here, here is a way in which you can add the "object_detection" path permanently to the PYTHONPATH variable.
If you are using a Linux system, here is how you would go about it:
Go to the Home directory. Press Ctrl + H to show hidden files. You will see a file called ".bashrc". Open this file using a code editor (I used Visual Studio).
In the last line of .bashrc file, add the line:
export PYTHONPATH=/your/module/path:/your/other/module/path:your/someother/module/path
Then press "save" in the code editor. Since ".bashrc" is a "Read-only" file the editor will throw a pop-up saying the same. Also in the pop-up there will be an option that says: "Try with sudo". Hit this button and now you are good to go.
All your modules are now permanently added to the PYTHONPATH. This means that you need not run sys.path.append every time you open your terminal and start a session!
Below is the screenshot with no error when I followed the said steps:
Try this. I hope it helps.
And finally, If you've followed all the steps here and are at your wit's end...make sure the file that you're running (the one with your source code in it ya know), isn't named object_detection.py - that would preclude it being searched for as a module.
Certainly I've never done anything like this that led me to add an embarrassing answer on Stack Overflow...
I had to do:
sudo pip3 install -e . (ref)
sudo python3 setup.py install
System:
OS: Ubuntu 16.04, Anaconda (I guess this is why I need to use pip3 and python3 even I made virtual environment with Pyehon 3.8)

Anaconda doesn't find module cv2

I am using Anaconda on OS X Mavericks. When I try loading cv2 I get an import error (see below). Do you know how to fix this?
>>import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dlopen(/usr/local/Cellar/opencv/2.4.8.2/lib/python2.7/site-packages/cv2.so,
2): Library not loaded: /usr/local/lib/libpng15.15.dylib
Referenced from: /usr/local/Cellar/opencv/2.4.8.2/lib/libopencv_highgui.2.4.dylib
Reason: image not found
I am not sure it's relevant, but in /usr/local/lib/ I have libpng16.16.dylib instead of libpng15.15.dylib.
This is the solution I found:
comment the PYTHONPATH environment in ~/.bash_profile, as suggested by #asmeurer
install opencv using https://binstar.org/jjhelmus/opencv
As suggested in this issue, I fixed this problem by simply executing
conda update hdf5
you could also just add it to your PYTHONPATH. here's how:
you should be able to get it to load through one of the other (non anaconda) python executables. mine were located at:
/usr/bin/python (default system python) and /usr/local/bin/python (brew)
call the python executable using the full path
once you successfully import cv2 run: cv2.__file__
this will give you the file's path which you can then take (full directory path not including filename) and add as the first argument to your PYTHONPATH defined in ~/.bash_profile
after changing the .bash_profile don't forget to run
source ~/.bash_profile to make the changes effective
fire up anaconda python and it should now find cv2

ImportError: No module named stack

I have a code in python that I have been working on and it builds and runs very well on my pc (Windows). I had to run the same code on my other machine which runs ubuntu,so I had to install all the packages on prior to runing the code. The problem is I ran into this error which I couldn't figure out. The error is triggered by one of the installed packages.
from qalsadi import analex
File "/usr/local/lib/python2.7/dist-packages/qalsadi/analex.py", line 14, in <module>
import pyarabic.araby as araby # basic arabic text functions
File "/usr/local/lib/python2.7/dist-packages/pyarabic/araby.py", line 28, in <module>
from stack import *
ImportError: No module named stack
I used the following command, "sudo pip install pyarabic", to install it. However, still the file stack.py doesn't exist among it's files. I searched in the folder /usr/local/lib/python2.7/dist-packages/pyarabic. The folder contains the following: araby.py and init.py and the coresponding pyc files only. I'v insalled and uninstalled it a number of times using "pip" but still the file is not there.
Check your pyarabic folder. Usually it's in Python27\Lib\site-packages\pyarabic.
There, there should be stack.py. If it doesn't exists, re-download pyarabic and then reinstall it.
After installation of pyarabic import STACK in this manner:
from pyarabic.stack import Stack
for window users
open cmd prompt and type the following to install the stack variable to python 3.x-
pip install pyarabic
To install and run with this code-
from pyarabic.stack import Stack
It seems like stack is not part of the Python Package Index so most probably it is a script you installed manually. The problem can be that the folder containing stack.py is not on your PYTHONPATH.
Open a terminal (Ctrl+ Alt + t) and edit the .bashrc file:
sudo gedit ~/.bashrc
Add the following line:
export PYTHONPATH=$PYTHONPATH:/path/to/the/folder/of/your/module
where you should substitute the part after the : to the full path to the directory
where stack.py can be found.
I hope this helps.

img2pdf.py "no module named Image"

Hello I am running Python 2.7 64 bit on windows 7. I've found a python script online called img2pdf.py which could be very useful to me but I can't run it. I've installed the Pillow library for win64 (from http://www.lfd.uci.edu/~gohlke/pythonlibs/)
and Image.py is present in "C:\Python27\Lib\site-packages\PIL"
I've downloaded the script to a directory containing my image, and python is on my path but when I type
python img2pdf.py myimage.j2k
at the command prompt I get an error that states
Traceback (most recent call last):
File "img2pdf.py" line 18, in <module>
import Image
ImportError: No module named Image
What have I missed?
On the Pillow library link, it is written:
Note: use from PIL import Image instead of import Image.
But when I look to the img2pdf.py script that I've found here, it is written import Image. So I guess you have to edit your img2pdf.py as specified above.
Install Python for Windows, e.g. "python-3.5.0-amd64.exe" --> C:\Python
Extract the zipped archive for img2pdf to C:\Python\Sources\img2pdf
Go to C:\Python\Scripts
Run pip.exe install ..\Sources\img2pdf
The package is now available from command line as "img2pdf.exe" in C:\Python\Scripts
