How to install numpy to Python 3.5?
Although using virtual environment is advisable in many use-cases, it is not strictly required. You can have a system python3.5 and a pip installation associated with it.
Note that Python 3.5 is now end-of-life and pip has now dropped support. The final version of pip supporting Python 3.5 was 20.3.4 (Jan 2021).
- Download this file:
pip-20.3.4-py2.py3-none-any.whl - Bootstrap a pip installation using the wheel file:
sudo python3.5 pip-20.3.4-py2.py3-none-any.whl/pip install pip-20.3.4-py2.py3-none-any.whl - Install numpy with
python3.5 -m pip install --user numpy
I strongly recommend using a virtual environment and in the case of the scientific Python stack, I further recommend using anaconda. It will save you loads of headaches in the future.
- Download anaconda for Python3.5.
- Create an environment.
- Activate it.
conda install numpy.
Step 2 looks like this:
conda create --name env_name numpy
Step 3 looks like this:
source activate env_name
Step 4 looks like this:
conda install numpy
Now, anytime you want to use numpy or any other dependency in your environment, you just do source activate env_name.
To deactivate, do:
source deactivate
