Spyder (4.1) does not work anymore with python 2.7 in Anaconda environnement.
When I launch spyder it does not open and I do not have any message.
If I launch spyder with python 3.8 it works.
conda environment :
What can I do?
Python 2 has officially been retired as one can see in PEP 373, but if it is necessary to use python 2 you could try using an older version of the spyder package. If you wish to use your code in the long-term it is highly advised to migrate necessary to python 3. I hope this helped
I was hoping for some help in setting up a Python development environment on a Mac.
Background: I'm running a newly upgraded macOS Sierra 10.12.1, and setting up various parts of Python development on it. This macOS version already came with Python 2.7.10 installed - and I'd prefer to leave that alone for now.
So I installed Homebrew, and then used that in turn to install the latest python3, that is, Python 3.5.2; but I guess it's not the default for Terminal yet, since when I run the python -V command, I get this in the Terminal window:
Python 2.7.10
So now I've got at least 2 version of Python on my Mac, and that's fine I guess, but the latest Python one is not the one that is the 'default'. How do I set 3.5.2 as my default rather than 2.7.10?
(Backstory for why I want to do that... pip is not installed, i.e., when I go to Terminal and type in pip, it says:
-bash: pip: command not found
When I tried to follow the installation instructions for pip, I ran into a permissions issue, which makes sense I guess, since I don't have access to the Mac's 2.7.10 Python install, nor do I really want it at this stage. So I'd like to switch Terminal to take the new Python 3.5.2 as my default one, in which case I guess I won't have pip permissions issues...)
Thanks in advance for any help folks!
The safest solution is to create a virtual environment running python 3 and use it as development environment. Check the following links:

I use Ubuntu 14.04. I had installed both Python 2.7 and Python 3.4 versions. I also had ipython installed (which was using Python 2.7 by default). Later I installed ipython3 using
sudo pip3 install ipython
and now I have ipython3. But when I only run ipython, it uses Python 3.4 (as opposed to 2.7). How to make default ipython use Python 2.7?
open .bashrc and add in the bottom
alias ipython='/usr/local/bin/ipython2.7'
before adding check confirm name ipython name of version 2.7 in /usr/local/bin
I fired up a new Windows google compute engine instance. It's running Windows 2008 R2, service pack 1.
I download and try running the Python .msi installer for version 2.7.9, and it fails with this error:
There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
I see this error for both the 64-bit and the 32-bit installer.
Has anyone else seen it or know of a work-around?
I reproduced your issue and I found two workarounds:
You can install python 2.7.6 successfully without further action.
If you need python 2.7.9 you can install it deselecting pip from the install menu.
This seems to be related to this answer in another thread although in that case the issue is with version 3.4.
Install python EXCEPT "pip"
Run the python install msi again and select "change"
Select "pip" and install the pip
It would be works...
I think it is a priority problem into the msi package...the package seems to try to install the pip before installing python.exe. So, pip can not be installed...
I'm using Windows 8.1 64-bit. I had 2.7.11 installed and then I tried to install PIP as well via Chocolatey PIP package.
I think my installation had got messed up because I had tried to install Python 3.4 as well as Python 2.
Then I had deleted all the Python 2 and Python 3 files in an attempt to get rid of this.
What worked for me was:
Editing the Environment Variables both, System and User to remove any PYTHONHOME or PYTHONPATH variables
I also deleted the path I had to python2 in the PATH environment variable
Now (as mentioned in Python Issue 22329) after deleting the Environment variables you can go into 'Programs and Features', click on the Python 2.7.11 (64-bit) program and then click 'Repair' - this then worked as I would expect without error.
Now finally I was able to go into 'Programs and Features', click on the Python 2.7.11 (64-bit) program and then click 'Uninstall'.
Edit: I assume this is connected with this PYTHON_HOME answer to a problem with Python 3.4
It seems to be a dependency issue, please try to install "Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)"
I followed these instructions to set up GraphLab on my Ubuntu machine. At the end, I opened Python 2.7.6 and ran the first of the test lines import graphlab as gl. This gave me
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named graphlab
How can I begin to diagnose this?
Details:
I ran python -V from a terminal, and it returned me Python 2.7.6.
In /usr/bin I find the following pyth* entries ... I wonder if something somewhere pointed at the wrong version:
python python2.7-config python3.4 python-config
python2 python2-config python3.4m pythontex
python2.7 python3 python3m pythontex3
The Dato Graphlab Create installer did not actually install graphlab on my Mac (El Capitan). I did the following (Anaconda is installed) in a terminal window:
% pip install graphlab-create
That subsequently installed Graphlab Create. You can then easily verify:
% python

>>> import graphlab

I've noticed that occasionally, Python will forget that Graphlab Create is installed. A repeat of the above 'pip' command will cause it to remember.
python anaconda graphlab
Another option is to use virtualenvwrapper for the easy creation and application of virtual environments. For example, following this documentation, start with installation:
sudo pip install virtualenvwrapper
Open your .bashrc settings file, for example run gedit .bashrc and append the following lines to the bottom of it:
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh
Restart your terminal window, and then you can make your virtual environment, say call it "test":
mkvirtualenv test
Now test is a virtual environment, and your are in it (i.e., test is "activated" currently). To put GraphLab in test,
pip install graphlab-create
Similarly, you can install other python toolkits in test by using pip, and any python program you run from within test will be able to see only the python toolkits that are installed here.
Maybe you should install graphlab in virtualenv.
1.Ensure your system has virtualenv installed. To verify, execute pip freeze. To install, execute sudo pip install virtualenv in your terminal before proceeding
2.Copy and execute the following commands in your terminal. This will create a virtual environment called 'graphlab' and install graphlab create version 0.9.1
virtualenv graphlab
. graphlab/bin/activate
pip install graphlab-create==0.9.1
You may need to activate the conda env by running
source activate dato-env
inside the terminal
Check your system path
import sys
print sys.path
It should contain graphlab-0.9.1. If not, then something was odd with our installation. I recommend using a virtual environment in python.
I had the same problem on ubuntu 16 desktop. The solution for me was pretty simple. After you start the notebook using
(gl-env) davis#smeagol:~/progs/ml-foundations$ jupyter notebook
Click the file navigator to locate your notebook where you do the import graphlab which causes the error. When it starts the notebook I imagine you see |Python [Root] in the top right. To fix this, click the title bar Kernel->Change kernel->gl-env. Now the top right label should say |Python [gl-env]. Afterwards when you run the notebook import graphlab will work.
There is a tab on the intial landing page of the Jupyter UI which has Conda. In that you can see two env's named root and gl-env. I've tried to delete the root one and even though its not the default all my notebooks start up with that environment and deleting it causes an internal error.
Graphlab is not supported on python3. Install Python 2.7 as mentioned in
https://conda.io/docs/user-guide/tasks/manage-python.html
If you don't see graphlab, simply the path of the environment is not set on "dato-env" (rather it may be set on "root")
If you use "Launcher" application, on top left set "Environment" to "dato-env".
Well,I guess the thread is dead.
After tinkering w/ un/reinstallations a couple times, the only way I can get "import graphlab" to work reliably is to manually activate dato-env.
Open your terminal and type below command
source activate dato-env
Prior to this close all the jupyter notebook. I ascertain that dato-env is in effect when my bash prompt changes to: (dato-env) pydev#smruti:~$
Now on your Jupyter notebook try to do import graphlab,this will execute without showing import error.
Hope this helps!!
I had the same problems, but then I found that in the files that come along with the Machine Learning specialization (https://www.coursera.org/learn/ml-foundations/notebook/lGQH5/open-your-notebook-workspace-to-follow-along) there are some additional codes after which you don't get any errors:
import graphlab
Set product key on this computer. After running this cell, you will not need to re-enter your product key.
graphlab.product_key.set_product_key('your product key here')
Limit number of worker processes. This preserves system memory, which prevents hosted notebooks from crashing.
graphlab.set_runtime_config('GRAPHLAB_DEFAULT_NUM_PYLAMBDA_WORKERS', 4)
Output active product key.
graphlab.product_key.get_product_key()
I had the same problem. I follow these steps.
1.Install Anaconda 2.7 version. Then I created vitual environment and selected python 2.7 version.
2.After create virtual environment open terminal in and run pip install notebook.
3.Then I registered https://turi.com/ because Graphlab Create requires an academic license to use.Run the following command that is given by after registration in terminal.
pip install --upgrade --no-cache-dir https://get.graphlab.com/GraphLab-Create/2.1/your registered email address here/your product key here/GraphLab-Create-License.tar.gz
4.Run jupyter notebook.
5.import graphlab
6.Then I got an error.So i run graphlab.get_dependancies() command. After that restarted the kernel.
7.After above all steps I typed import graphlab again.
8.It executed without errors.
