I have minconda3 and python 3.8. I have been trying to install opencv through various ways and it is still not working. I used:
pip install opencv
pip install opencv-python
conda install py-opencv
I tried installing using wheel but couldn't find a version that satisfied. I keep getting this error:
dll load failed while importing cv2: The specified module could not be found.
conda Super Easy ✨Try creating a new environment first. If you are using conda, it is better to use conda install whenever possible over pip install. You need to specify the channel conda-forge for opencv (it has the most updated version on conda).
The following command should do it.
conda create -n opencv_env python=3.8 -c conda-forge opencv numpy matplotlib scipy
Once installed, activate the environment with conda activate opencv_env.
However, for reproducibility, I would encourage you to create an environment.yml file and create/update the environment easily whenever necessary. See here for more details on it.
Save the following as environment.yml file. And then run conda env create -f environment.yml from the same location as the environment.yml file.
### filename: environment.yml
#
### To create environment run:
# conda env create -f environment.yml
#
### To update environment run:
# conda env update -f environment.yml --prune
#
### Note:
# The --prune option causes conda to remove any
# dependencies that are no longer required from
# the environment.
#
### Activating the environment
# conda activate opencv_env
#
### Deactivating the environment
# conda deactivate opencv_env
name: opencv_env # <-- The name of the environment
channels:
- conda-forge
- defaults
dependencies:
- python=3.8
- opencv # -c conda-forge
- numpy
- matplotlib
- scipy
- pip:
# list packages for which "pip install <package>" is necessary
#- hypothesis
