how to change numpy version with miniforge

Question

I have installed miniforge on my mac , in that using a 'local env' on jupyter notebook. I can't change the numpy version (need to downgrade to 1.19.5) on this kernel, have tried: (1)pip install numpy==1.19.5 & (2)conda install -c conda-forge numpy=1.19.5.

numpy version seems to be changing easily on conda-ipython3 kernel, but my project is running on 'local env'

very new to all this, still learning. Please help

Answer 1

first make sure that your local environment is activated by running: .../{your venv folder path}/Scripts/activate . Because if you install numpy on the wrong virtual environment then it won't work. Then uninstall numpy by running pip uninstall numpy . Then install the numpy version you want.

Answer 2

You can do the following to ensure you have desired numpy version:

1. Activate your local environment
2. Uninstall any previously installed numpy version by using:

pip uninstall numpy

3. Install the desired numpy version:

pip install numpy=1.19.5

4. Check the installed version of numpy :

pip freeze

If you want to export the package list use:

pip freeze > requirements.txt
