installing cvxopt on windows 10 using anaconda python 3.* - windows

I've been trying to install cvxopt on Anaconda Python 3.x for a while now, reading past posts and I can't seem to make it work. Here is what I have tried so far:
pip install cvxopt --user
which gave me the following error:
Failed building wheel for cvxopt
Then I tried this:
conda install -c omnia cvxopt
output:
UnsatisfiableError: The following specifications were found to be in conflict:
- cvxopt
- python 3.5*
I installed mkl using this:
conda install mkl
which worked but trying out the previous commands still don't work.
I have installed multiple things in the past using the command prompt but my experience has told me to make sure I know and understand what I am installing because I wrecked my computer one time. So instead of trying things blindly, I would like to know if someone had a tipp.

As you can see here cvxopt does not support python 3.5+ due to compiler incompatibility.
Nevertheless, as stated in the comments, you can use anacodna to create a virtual environment and install it.
conda create --name py34 python=3.4 numpy
activate py34
conda install -c omnia cvxopt

How to install AutoKeras on aws-ec2

I tried to install autokeras on aws ec2 (p2.xlarge) with the environment python 3.6 & tensorflow. I get following error after "pip install autokeras":
tensorflow 1.10.0 has requirement numpy<=1.14.5,>=1.13.3, but you'll have numpy 1.15.4 which is incompatible.
Installing collected packages: imageio, autokeras
Found existing installation: imageio 2.3.0
Cannot uninstall 'imageio'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
I uninstalled numpy 1.15.4 and installed numpy 1.14.5. With "conda list", I can see the numpy has the correct version.
But after "pip install autokeras" I get the same error and numpy 1.15.4 is still there.
Has anyone successfully installed autokeras on aws ec2? What shall I do to install autokeras correctly?
(Maybe the 'imageio' is the next problem?)
Thank you!
I think you need tensorflow 1.14. Here my notes for AutoKeras installation:
Autokeras Installation Notes in the Deep Learning AMI:
We launched a new deep learning AMI with ubuntu.
The deep learning AMI didn't worked using the "tensorflow + keras + py3.6" environment (so no need for a DL AMI probably, you can save space on disk using a normal clean AMI), so we managed o install autokeras doing the following:
Create a new environment with Anaconda: $ conda create -n autokeras python=3.6.
1.1. Remember that only python 3.6 is working with autokeras
Activate virtual env: It didn't work $ conda activate autokeras, but it works using $ source activate autokeras.
installation of all the packages as required by pyimagesearch.
3.1. A new problem arised here, which, long story short, was solved using the next post (note that I chenged the order, since urllib3 needs jsonschema to be installed first):
$ pip uninstall urllib3```
$ pip uninstall jsonschema
$ pip install jsonschema==2.6.0
$ pip install urllib3==1.24.1
3.2. Finally I was able to install all 3 packages:
$ pip install tensorflow # or tensorflow-gpu
$ pip install keras
$ pip install autokeras
3.3. Autokeras worked fine at this point, but it raised a warning:
>>> import autokeras
Better speed can be achieved with apex installed from https://www.github.com/nvidia/apex
So I just went to the webpage and followed the installation steps. Now it works without warnings (so far):
$ git clone https://github.com/NVIDIA/apex
$ cd apex
$ pip install -v --no-cache-dir --global-option="--pyprof" --global-option="--cpp_ext" --global-option="--cuda_ext" ./

Basemap install on mac without fink (I tried everything I can google)

I am a Python Noob. (Using Mac OS 10.12 & Python 3.7)
I'm trying to use mpl_toolkits.basemap
to execute the code
from mpl_toolkits.basemap import Basemap
I googled the way to get matplotlib and successfully installed it.
However, while it's possible to run "from mpl_toolkits.basemap import Basemap" in terminal on mac,
it fails to be loaded if I run the command within IDLE.
Then, I googled to figure out the issue and got the hint that
it could be resolved if I install Basemap properly.
To install Basemap, I think I need to go with "FINK".
However, Fink is only available up to 10.5 OS while mine is 10.12.
And FINK website says do not update OS before upgrading FINK.
However, it's too late for me.
Cause I updated my OS longtime ago and recently I started to learn Python Using Mac.
So I guess, if there is a way to install Basemap not using apt-get,
(the codes below is from "Python basemap module impossible to import")
sudo apt-get install libgeos-3.5.0
sudo apt-get install libgeos-dev
sudo pip install https://github.com/matplotlib/basemap/archive/master.zip
I think my issue could be cleared.
Since I'm really really noob, I'm not sure this is the reason for my failing in "from mpl_toolkits.basemap import Basemap".
What I tried so far is
1) brew install basemap
with the error of
Error: No available formula with the name "basemap"
==> Searching for a previously deleted formula (in the last month)... Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
2) pip install basemap
with the error of
Requirement already satisfied
3) sudo pip install https://github.com/matplotlib/basemap/archive/master.zip
with the error of
Command "python setup.py egg_info" failed with error code 1 in
/private/tmp/pip-install-lux494o4/pyproj/
4) conda install basemap
with the following message of
All requested packages already installed.
5) conda install -c conda-forge basemap
with the following message
Preparing transaction: done Verifying transaction: done Executing
transaction: done
Can anyone help to install basemap properly so that I could run
"from mpl_toolkits.basemap import Basemap"
in my IDLe?
My IDLE Sheel keeps saying
Traceback (most recent call last): File "", line 1, in
from mpl_toolkits.basemap import Basemap ModuleNotFoundError: No module named 'mpl_toolkits.basemap'
while my terminal doesn't have problem with running the code.
Appreciate it in advance.
any luck? I spent the day battling this as well. I had the most success when I tried downloading an older version of basemap.
I was using python 2.7 and this worked okay sudo -H pip2 install https://github.com/matplotlib/basemap/archive/v1.1.0.tar.gz
For python 3 try replacing pip2 with pip3 or pip.
Ran into this myself today my solution:
install libgeos on mac
brew install geos
then as you suggested use pip to install mpl_tools:
pip3 install -q https://github.com/matplotlib/basemap/archive/master.zip
This also may help:
missing libgeos_c.so on OSX
Firstly, I suggest you to set Anaconda up. Then follow below steps;
Create a new environment in anaconda.
Install Jupyter Notebook and launch it. If it works, turn it off.
Change your anaconda environment in your terminal.
Try installation commands below;
conda install ...
conda install forge ...
pip install ...

Installing tensorflow on anaconda/mac?

I can not find a solution to install tensorflow on anaconda/mac.
When i try: conda install tensorflow,
I get:
UnsatisfiableError: The following specifications were found to be in conflict:
- blaze -> numba -> numpy=1.13
- tensorflow
Use "conda info " to see the dependencies for each package.
I tried reinstalling numpy, and could not find any relevant documentation.
On mac use following command:
conda install -c conda-forge tensorflow
This will install the latest Tensorflow on your system. if you wish to upgrade it to newer version then you can use the following command
conda update -f -c conda-forge tensorflow
I have had success installing tensorflow through pip...
pip install tensorflow
or, if you have all of the proper libraries...
pip install tensorflow-gpu
But if you have already removed numpy form the anaconda install, you might be in for a long day because almost all of the numeric packages require it. If the above pip install doesn't work, you might want to start from a clean anaconda install.
I have installed tensorflow using -
pip install tensorflow
Or, you can use Anaconda in following way -
Open Anaconda Navigator
On Left side go to Environments
Create a new environment (eg :- tensorflow_tf), select python 3.7
then select Not installed and Search "tensorflow"
click on tensorflow and apply

conflict while installing mayavi into anaconda

Good day,
My colleague asked my to install Anaconda and mayavi and I am novice with this topic and I decided to do the tasks on a new ubuntu installation
Here are my tasks before my issue
I fresh installed a Ubuntu 16.04
I ran all update apt-get update/upgrade
I created an user account (anna) and add it in sudo group
I loged into anna account
I downloaded Anaconda2-4.4.0-Linux-x86_64.sh for python 2.7
I installed with the command sudo bash Anaconda2-4.4.0-Linux-x86_64.sh
I installed anaconda in /opt/anaconda2 instead to the /home/anna/anaconda2 (for all user usage) and I say YES to have the line export PATH="/opt/anaconda2/bin:$PATH" in .bashrc file of anna
I run source /home/anna/.bashrc
After the anaconda installation, I could see a successful message regarding the installation
Now my colleague asked me to install mayavi and she provided me the following link mayavi
Then I simply enter the following command
conda install -c anaconda mayavi=4.5.0
And here start my problem. I can not well understand the conflict but apparently there is a conflict and I have no idea how to solve it. Here is the command and the message
anna#pc17:~$ conda install -c anaconda mayavi=4.5.0
Fetching package metadata ...........
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- mayavi 4.5.0* -> pyqt 4.* -> qt >=4.8.6,<5.0
- mayavi 4.5.0* -> pyqt 4.* -> sip >=4.16.4,<4.18
- navigator-updater -> pyqt >=5.6 -> qt 5.6.*
Use "conda info <package>" to see the dependencies for each package.
I have no idea what does mean the above message and how to solve me problem.
Is there depencies that I have to additionally install?
For information the above command return me this:
anna#cryospc17:~$ python --version
Python 2.7.13 :: Anaconda 4.4.0 (64-bit)
anna#cryospc17:~$ python3 --version
Python 3.5.2
Did I correctly try t install mayavi?
Thank a lot for any help you can provide me
To complete the install of mayavi, you have to first install the following depence
conda install -c anaconda vtk=6.3.0
conda install -c anaconda pyside=1.2.1
Then install mayavi
conda install -c anaconda mayavi=4.5.0
It may possible, you have to remove pyqt
conda uninstall pyqt
We finally could install anaconda and mayavi sucessfully.
I hope it help
Cheers
This might be helpfull to others. It must be anaconda for python 2.7 currently and the follows worked.
Install anaconda for python 2.7, then try the follows:
conda uninstall pyqt
conda uninstall navigator-updater
conda install pyqt=4
conda install vtk
conda install envisage
conda install pyside
conda install apptools=4.4.0
conda install mayavi

Distribute and Pip for use with Python 3.2

When installing modules with pip or distributes easy_install for python3, modules will instead install for python 2.7 or earlier. Im fairly new to both the mac operating system and python itself (4 months or so). I'd like to get distribute and pip installed and working for python 3.2.
When using easy_install or pip, things will work normally with installing for python 2.7. This is not what I wanted however and I tried to fix this by installing both pip and easy install with:
sudo curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python3
as opposed to
sudo curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python
This should accomplish what i wanted to do, however, after installing like that I get:
new-host-6:~ Eric$ pip install spynner
-bash: pip: command not found
If anyone has any experience with the above stated in getting pip and distributes easy_install to work for python3, help would be much appreciated.
