ERROR: Package 'imageio' requires a different Python: 2.7.17 not in '>=3.5'

I am doing Medical Image Analysis, in that I need package imageio in jupyter notebook. I am writing this command

!pip install imageio

Giving me error like this

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

Collecting imageio
  Using cached imageio-2.9.0.tar.gz (3.3 MB)
ERROR: Package 'imageio' requires a different Python: 2.7.17 not in '>=3.5'

My kernel Jupyter one set to Python3

!python3 --version 
Python 3.6.3 :: Anaconda, Inc.

I tried

!pip3 install imageio

which correctly Installed it with this output

Requirement already satisfied: imageio in /home/jayakumars/anaconda3/envs/fastai2/lib/python3.6/site-packages (2.15.0)
Requirement already satisfied: numpy in /home/jayakumars/anaconda3/envs/fastai2/lib/python3.6/site-packages (from imageio) (1.19.5)
Requirement already satisfied: pillow>=8.3.2 in /home/jayakumars/anaconda3/envs/fastai2/lib/python3.6/site-packages (from imageio) (8.4.0)

But still when import imageio package

import numpy as np
import pandas as pd
import os
import matplotlib.pyplot as plt
import glob
import nibabel as nib
import cv2
import imageio
from tqdm.notebook import tqdm
from ipywidgets import *
from PIL import Image
from fastai.basics import *
from fastai.vision.all import *
from fastai.data.transforms import *

Giving me ImportError

ImportError                               Traceback (most recent call last)
<ipython-input-40-9c1456a18eb5> in <module>()
      6 import nibabel as nib
      7 import cv2
----> 8 import imageio
      9 from tqdm.notebook import tqdm
     10 from ipywidgets import *

ImportError: No module named imageio

So, How can I install it?

I tried pip3 and I was expecting to remove imageio ``importError

You are getting this error because Jupyter Notebook is installed for your system Python (/usr/bin/python), not for your conda environment (/home/jayakumars/anaconda3/envs/fastai2/bin/python). Therefore when you started Jupyter Notebook with jupyter notebook --no-browser --port=8878, even though you had run conda activate fastai2, it was still running the Jupyter Notebook installed for the global Python, and therefore your code was also running in the global python. You can check this by running import sys and print(sys.executable).

To run your code inside the fastai2 environment, the easiest way at least is to install Jupyter Notebook inside the environment and run that. So run conda activate fastai2 and then inside the environment run pip install notebook (or to be safe, /home/jayakumars/anaconda3/envs/fastai2/bin/pip install notebook).

Then you should be able to run jupyter notebook --no-browser --port=8878 inside the env (or to be safe, /home/jayakumars/anaconda3/envs/fastai2/bin/jupyter notebook --no-browser --port=8878). You can verify that your code is running in the environment with import sys and print(sys.executable) again.

Finally, you may need to install the packages you were using (numpy, pandas, matplotlib, nibabel, etc.) in the fastai2 environment, since they may not be installed yet. You can do this with pip install in the environment (or to be safe, /home/jayakumars/anaconda3/envs/fastai2/bin/pip install). You can also run these commands using ! from inside jupyter notebook.
