Attribute error on module cvlib

[Kidist-Abraham]

hey @arunponnusamy I installed cvlib via pip and try a simple code like

import cvlib as cv import cv2

cap=cv2.VideoCapture("std_camera.mp4") while True: ret,image=cap.read() faces, confidences = cv.detect_face(image) print(faces) print(confidences)
if cv2.waitKey(1) & 0xFF==ord('q'): break cv2.release() cv2.destroyAllWindows()

but it has an attribute error logging module 'cvlib' has no attribute 'detect_face'

I also tried it with python3 but still got that error.

[arunponnusamy]

Hello @Kidist-Abraham , this is weird. Have you installed the dependencies ? pip install numpy opencv-python requests progressbar I would suggest to stick to Python3 for using cvlib. Are you using pip3 for installing the package for python3 ?

[Kidist-Abraham]

hey, The problem was the name of my python code. It was cvlib.py. I think the program took my code as the cvlib module. Anyway i changed the name and it works fine. Thank you.

[mrudhula]

@arunponnusamy with that pkg 'pip install numpy opencv-python requests progressbar' also my problem is not getting solved 'ModuleNotFoundError: No module named 'cvlib''

[arunponnusamy]

@mrudhula May I know the python version you are working with and the command you are trying to execute to run the script ?

import cvlib as cv

Its not working..Help me to fix the error.

@suvodeepdebnath Can you check whether Keras has been installed properly ?

import keras
print(keras.__version__)

[AnalyticsInAction]

I have the same "No module named 'cvlib'` error.
Exact traceback from my conda virtual environment is

(cvlibenv) C:\Users\Steve\Desktop\Python Projects\cvis>testcv.py Traceback (most recent call last): File "C:\Users\Steve\Desktop\Python Projects\cvis\testcv.py", line 1, in <module> import cvlib ModuleNotFoundError: No module named 'cvlib'

When checking if Keras if properly installed via the script below I get : " 2.2.4-tf"

import tensorflow as tf print(tf.keras.__version__)

As for some additional background, when I 'conda list' to summarize libraries installed I get the following list of packages and versions. Note I am running Tensor flow 1.14.0, but also get the same error in a tensorflow 2.0.0 environment as well.

Any ideas?

[arunponnusamy]

@AnalyticsInAction I haven't actually tested with conda. Can you try installing cvlib via pip ?

[AnalyticsInAction]

I installed cvlib via pip when I got that error (cvlib doesn't appear to be an option via conda). The rest of the required packages were installed via conda.

I did wonder whether this was something linked to the conda virtual environment, and tried to do an cvlib install in a "VENV" virtual environment (with the following method)

python -m venv cvliben cvliben\Scripts\activate.bat pip install opencv-python tensorflow pip install cvlib

but using this methodology - I get another error "ModuleNotFoundError: No module named 'keras.utils'; 'keras' is not a package"

if I pip list the following package versions are listed `(cvliben) C:\Users\Steve\Desktop\Python Projects\cvis>pip list Package Version

I also tried uninstalling and reinstalling Keras with

pip uninstall keras pip install keras --upgrade

but the error persisted.

Perhaps its a conflict between different version permutations? Could you outline the exact versions of Python, Tensorflow, Opencv, and Cvlib you are using in your current environment. I will l see if replicating it might resolve my current issues.

Cheers Steve

[arunponnusamy]

This seems to be a weird issue on Windows. Can you try importing keras on a python console just to check it is properly installed.

$python3
>>import keras
>>print(keras.__version__)

Also if possible can you try using cvlib on linux/macos ? or probably on Google Colab ? I am using

Python 3.6.8, 
TensorFlow 1.15.0
opencv-python 4.1.0.25
keras 2.2.4
cvlib 0.2.3

[AnalyticsInAction]

Thanks for the additional suggestions. I will be offline for the Christmas break, but will revisit these suggestions once I am back online. Cheers Steve

[AnalyticsInAction]

Yes - works fine in Colab. Simple test here : Might just side step the issue and run in Linux environment rather than windows. Cheers Steve

[arunponnusamy]

I think it should also work on Windows with the plain command prompt and pip (without any other external things like Anaconda).

[AnalyticsInAction]

Thanks. I set up a virtual environment using VENV on my Windows 10 machine, and installed the exact versions you specified above - and cvlib now works fine. So I will put it down to some interaction between library versions. Thanks for your advice and suggestions.

[arunponnusamy]

@AnalyticsInAction Are you using Anaconda for this setup ?

[AnalyticsInAction]

@arunponnusamy Apologies, thought I had replied to the last message weeks ago. The setup that worked didn't involve Anaconda. Just standard pip install in a VENV virtual environment using a requirements file to specify the exact versions of the libraries you outlined above.

so

1. Create a new environment python -m venv cvliben

2. Navigate to the directory cd C:\Users\Steve\Desktop\Python Projects\cvis

3. Activate the virtual environment cvliben\Scripts\activate.bat

4. Install the requirements.txt file pip install -r requirements.txt

Then I just ran the cvlib scripts and everything worked. Cheers Steve

[AISWARYA2019]

I got the same error while importing "cvlib". import cvlib Please help, thanks.
