On my Mac M1 (Monterey) I have created a new virtual environment with
virtualenv --python=/opt/homebrew/bin/python3.8 ~/.virtualenvs/datascience_env
to link it with specific Python 3.8 version. Now I'm trying to install tensorflow. The following command (issued in the virtual environment):
(datascience_env)% pip install tensorflow
causes the following error:
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow
Just to be sure, I also did:
(datascience_env)% python -c "import sys; print(sys.version)" or python -c "import struct; print(struct.calcsize('P')*8)"
and the output confirms the 3.8 version:
3.8.14 (default, Sep 6 2022, 23:17:06)
[Clang 13.1.6 (clang-1316.0.21.2.5)]
I've finally opted for a simpler solution. I followed here the procedure to install Tensorflow on Mac M1 with miniforge. Works like a charm. In summary the steps are install miniforge, then:
conda config --set auto_activate_base false
conda create --name mytfenv python=3.8
conda activate mytfenv
conda install -c apple tensorflow-deps
pip install tensorflow-macos
pip install tensorflow-metal
conda install -c conda-forge -y pandas jupyter
The current default version of Python running on Google Colab is 3.7, but I need 3.9 for my notebooks to work.
How can I update Google Colab's Python version to 3.9 (or greater)?
In Google Colab you have a Debian-based Linux, and you can do whatever you can on a Debian Linux. Upgrading Python is as easy as upgrading it on your own Linux system.
Detect the current python version in Colab:
!python --version
#Python 3.8.16
Install new python version
Let's first install and upgrade to Python 3.9:
#install python 3.9
!sudo apt-get update -y
!sudo apt-get install python3.9
#change alternatives
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2
#check python version
!python --version
#3.9.16
Port Colab kernel to the new installed python
As mentioned in the comments, the above commands just add a new python version to your google colab and update the default python for commandline usage. But your runtime packages such as sys are still running on the previous python version. The following commands need to be executed as well, to update the sys version.
# install pip for new python
!sudo apt-get install python3.9-distutils
!wget https://bootstrap.pypa.io/get-pip.py
!python get-pip.py
# credit of these last two commands blongs to #Erik
# install colab's dependencies
!python -m pip install ipython ipython_genutils ipykernel jupyter_console prompt_toolkit httplib2 astor
# link to the old google package
!ln -s /usr/local/lib/python3.8/dist-packages/google \
/usr/local/lib/python3.9/dist-packages/google
Now you can restart runtime and check the sys version. Note that in the new python version you have to install every packages, such as pandas, tensorflow, etc. from scratch.
Also, note that you can see a list of installed Python versions and switch between them at any time with this command:
(If nothing changed after installation, use this command to select python version manually)
!sudo update-alternatives --config python3
#after running, enter the row number of the python version you want.
It's also possible to update the kernel without going through ngrok or conda with some creative package installation.
Raha's answer suggesting making a link between the default google package and the newly installed Python version is the trick that makes this work because, at least with Python 3.9, the version of pandas (0.24.0) that the google package requires fails to build.
Here's the code I used to install and switch my Colab kernel to Python 3.9:
#install python 3.9 and dev utils
#you may not need all the dev libraries, but I haven't tested which aren't necessary.
!sudo apt-get update -y
!sudo apt-get install python3.9 python3.9-dev python3.9-distutils libpython3.9-dev
#change alternatives
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2
#Check that it points at the right location
!python3 --version
# install pip
!curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
!python3 get-pip.py --force-reinstall
#install colab's dependencies
!python3 -m pip install ipython ipython_genutils ipykernel jupyter_console prompt_toolkit httplib2 astor
# link to the old google package
!ln -s /usr/local/lib/python3.8/dist-packages/google \
/usr/local/lib/python3.9/dist-packages/google
# There has got to be a better way to do this...but there's a bad import in some of the colab files
# IPython no longer exposes traitlets like this, it's a separate package now
!sed -i "s/from IPython.utils import traitlets as _traitlets/import traitlets as _traitlets/" /usr/local/lib/python3.9/dist-packages/google/colab/*.py
!sed -i "s/from IPython.utils import traitlets/import traitlets/" /usr/local/lib/python3.9/dist-packages/google/colab/*.py
If Google updates from Python 3.8, you'll have to change the path to the default package.
Then go the Runtime menu and select Restart runtime. It should reconnect and choose the updated version of Python as the default kernel. You can check that it worked with:
#check python version
import sys
print(sys.version)
!python3 --version
!python --version
To use another python version in google colab, you need to:
1- Installing Anaconda.
2- Adding (fake) google colab library.
3- Starting Jupyterlab.
4- Accessing it with ngrok.
# install Anaconda3
!wget -qO ac.sh https://repo.anaconda.com/archive/Anaconda3-2020.07-Linux-x86_64.sh
!bash ./ac.sh -b
# a fake google.colab library
!ln -s /usr/local/lib/python3.6/dist-packages/google \
/root/anaconda3/lib/python3.8/site-packages/google
# start jupyterlab, which now has Python3 = 3.8
!nohup /root/anaconda3/bin/jupyter-lab --ip=0.0.0.0&
# access through ngrok, click the link
!pip install pyngrok -q
from pyngrok import ngrok
print(ngrok.connect(8888))
you can also use:
# Install the python version
!apt-get install python3.9
# Select the version
!python3.9 setup.py
another way is to use a virtual environment with your desired python version:
virtualenv env --python=python3.9
Update 24.12.2022 - Unfortunately, the method does not work anymore.
This worked for me (copied from GitHub), I successfully installed Python 3.10.
#The code below installs 3.10 (assuming you now have 3.8) and restarts environment, so you can run your cells.
import sys #for version checker
import os #for restart routine
if '3.10' in sys.version:
print('You already have 3.10')
else:
#install python 3.10 and dev utils
#you may not need all the dev libraries, but I haven't tested which aren't necessary.
!sudo apt-get update -y
!sudo apt-get install python3.10 python3.10-dev python3.10-distutils libpython3.10-dev
!sudo apt-get install python3.10-venv binfmt-support #recommended in install logs of the command above
#change alternatives
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 2
# install pip
!curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
!python3 get-pip.py --force-reinstall
#install colab's dependencies
!python3 -m pip install setuptools ipython ipython_genutils ipykernel jupyter_console prompt_toolkit httplib2 astor
#minor cleanup
!sudo apt autoremove
#link to the old google package
!ln -s /usr/local/lib/python3.8/dist-packages/google /usr/local/lib/python3.10/dist-packages/google
#this is just to verify if 3.10 folder was indeed created
!ls /usr/local/lib/python3.10/
#restart environment so you don't have to do it manually
os.kill(os.getpid(), 9)
In addition to Kaveh's answer, I added the following code. (This colab python version is python 3.8 and I tried to downgrade to python 3.7)
!pip install google-colab==1.0.0
# install colab's dependencies
!python -m pip install ipython==7.9.0 ipython_genutils==0.2.0 ipykernel==5.3.4 jupyter_console==6.1.0 prompt_toolkit==2.0.10 httplib2==0.17.4 astor==0.8.1 traitlets==5.7.1 google==2.0.3
This way, I solved the crashing runtime error.
Simple as that: -
!wget -O mini.sh https://repo.anaconda.com/miniconda/Miniconda3-py39_4.9.2-Linux-x86_64.sh
!chmod +x mini.sh
!bash ./mini.sh -b -f -p /usr/local
!conda install -q -y jupyter
!conda install -q -y google-colab -c conda-forge
!python -m ipykernel install --name "py39" --user

How can I Download and install numpy and pandapower on the RASPBIAN JESSIE LITE Minimal image based on Debian Jessie? the one without the GUI. And how can I download and install Pip and miniconda on it as well?
um i am pretty sure the commands are the same are they not? Have you searched this up yet? i am sure that if you have another computer you can just search up miniconda and copy the download link and follow the instructions. pip is automatically installed in miniconda and if you dont have it do
sudo apt-get install python-pip
and for numpy do
pip -U install numpy
or
conda install numpy
for pandapower
conda install pandapower
pip -U install pandapower
or if you cant get miniconda with the method above just do
sudo apt-get install python
that will get you python and pip.
Good Luck!!
I am currently using the virtualenv intallation of tensorflow version r0.7. I would like to upgrade to r0.9 in virtualenv. What ia the procedure to do it?
The following should work :
# Once inside your virtualenv
(venv) $ pip uninstall -qy tensorflow
(venv) $ pip install -U https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.9.0-cp27-none-linux_x86_64.whl
That is, assuming you want the cpu version and using Python 2.7. Look here for other versions of the pip packages.
I've read in the documentation that Python3.4 ships with pip installed. When I try to make a call however I get an error. What am I missing?
U:\>py -V
Python 3.4.2
U:\>py -3.4 -m pip install matplotlib
C:\Python34\python.exe: No module named pip
