Syntax error while installing seaborn using conda - ipython

I've recently tried to install seaborn on ipython, which the latter was installed using anaconda. However, when I ran conda install seaborn, i was returned with a syntax error. I tried again with conda install -c anaconda seaborn=0.7.0 this time but syntax error was returned again. Apologies for my limited programming knowledge, but could anyone provide advice on how to resolve this issue?

conda is a command line tool, not a Python function. You should be typing these commands in a bash (or tcsh, etc.) shell, not in the IPython interpreter.

I can not install OpenMDAO

I have installed Anaconda since it was recommended to use in the OpenMDAO's website. After that I typed pip install 'openmdao[all]' as instructed. However I get an error message saying, "ERROR: Invalid requirement: "'openmdao[all]'"" I was wondering how can I solve this issue. I have no knowledge about the Python or anaconda therefore I don't have a clue what to do about this situation. I searched the internet however I didn't find a solution to this. Thanks in advance!
It's possible you're running the wrong pip executable. Try which pip - it should be located under your home directory instead of a system path such as /bin/pip or /usr/bin/pip.
Make sure you've created and activated an environment in Anaconda:
conda create -n myenv pip
conda activate myenv
python -m pip install 'openmdao[all]'
That command sequence will give the highest chance of success. The single quotes are required for shells like zsh.
Remove the single quotes:
pip install openmdao[all]

Trying to import docx in Python

Fair Warning: I am extremely new to python, so please excuse any dumb mistakes I make =)
I would like to be able to open/close/manipulate/read Word documents (docx files) on my Mac using Python. The python-docx module looked really useful, so I have been trying to install it on my system, to no avail.
Here's what I've done so far:
Checked that I do indeed have python installed using the python --version command in terminal. I have version 3.7.0, so all good there.
Checked that I do indeed have pip installed - I was able to use pip install and pip uninstall commands, so all good. I also upgraded my pip version using pip install --upgrade pip to pip-19.1.1
Following the online documentation (see here), I tried pip install python-docx. This seemed to work just fine, and after the progress bar loaded all the way I saw:
Successfully built python-docx
twisted 18.7.0 requires PyHamcrest>=1.9.0, which is not installed.
Installing collected packages: python-docx
Successfully installed python-docx-0.8.10
I wasn't completely sure what pyhamcrest was, but I installed it anyway just to be safe using pip install pyhamcrest
As other sites suggested, I also tried to install Pillow, lxml, and python-dateutil using their respective install commands, and in each case saw the Requirement already satisfied: message, with an anaconda path listed.
Frustrated, I also tried easy_install python-docx, the manual version, and even pip install docx . In all cases, when I run IDLE and type from docx import Document or just import docx, I get the following message in the shell:
`Traceback (most recent call last):`
`File "/Users/[my_name]/Desktop/Medical.py", line 3, in <module> `
`import docx`
`ModuleNotFoundError: No module named 'docx'`
Could anyone help point me in the right direction? Thank you very much.
The Anaconda Python distribution has its own system of installation of packages.
After the installation of Anaconda, the variable $PATH has been modified so that anaconda python was the first, and OsX's python in the last position.
If you type "python" in a shell will execute the anaconda python, instead of the standard OsX python (which is 2.7, not 3.x).
Following the instructions of the package python-docx, you have installed it using pip, which is the default method for installing packages, but this method is not valid for Anaconda Python. So, you finished installing python-docx for the python 2.7 of OsX.
To install packages for anaconda, you must run the command
conda install <package>
The python-docx module for anaconda can be found in a separated repository called conda-forge; typing the command
conda install -c conda-forge python-docx
you will install the package and the requested dependencies.
Other useful commands are:
anaconda-navigator for exploring the Anaconda system
anaconda-project for managing projects with anaconda
idle3 for Anaconda Python shell.
Before start coding, run anaconda-navigator and take a look at the 'Learning' section.
For a better experience, I suggest PyCharm IDE for Anaconda from JetBrains.

Using conda environment in IPython interactive shell

I am trying to use the interactive shell of IPython within my conda env and am having issues.
The steps I take are:
source activate myenv
conda install ipython
ipython
When I am in ipython interactive shell, it calls python from the anaconda root bin. (~/anaconda2/bin')
Is there anything I can do to change the python path to ~/anaconda2/envs/myenv/bin and import packages from myenv?
I see few solutions to making env work in jupyter when I search the web, but no answer on making it work on the interactive shell.
This is likely due to your $PATH variable being messed up.
THe easiest way to make sure you get IPython from within an env is to use $ python -m IPython <rest of the options> to start IPython. This works for many of the Python installable application; like pytest, pip and other.

Created an Anaconda python3 environment but it still loads ipython 2.7.6

So I installed Anaconda on my Ubuntu linux 12.04LTS x64 box. It seems to work fine except for this. So I created a conda environment using the
conda create -n py33dev python=3 anaconda
When I try to run the ipython shell, I would expect to get the Ipython3 shell and notebook. However, it still loads the ipython 2.7.6 shell. I tried using the ipython3 command, but it will then load an ipython3 shell from my computer and not from Anaconda.
I tried to install ipython3 to the Anaconda environment using
pip install ipython3
and
conda install ipython3
However, when I do this I just get a message saying "No packages found matching: ipython3"
So I am not sure why Anaconda runs fine with python2 but not with python3--even though Continuum indicates it is python3 ready. Am I missing a step anywhere? Does anyone know how to solve this?
Did you remember to do "source activate py33dev"?

ipython will not work even after reinstalling

Im trying very hard to get ipython notebook to work. I got it working in terminal, but I can't get it to work in my browser.
When I type ipython notebook in terminal, it says -bash: ipython: command not found
MacBook-Air:~ me$ sudo easy_install https://github.com/ipython/ipython/tarball/master
Downloading https://github.com/ipython/ipython/tarball/master
error: None
MacBook-Air:~ me$ ipython
-bash: ipython: command not found
Im really unsure why this is happening.
You do not need to (and you probably shouldn't) do sudo easy_install it will probably install things as root, avoid sudo. Check that ipython executable is in your $PATH.
github tarballs are broken for IPython. You do have to deep clone with git if you want to run master, then run python setup.py with the option you like (install, develop, symlink)...
Use pip if you want to run IPython stable.
You might have issues with readline on osx (wrong multiline editting, wrong completion, IPython popping error messages at launch time) this is one of the rare case where you might have to using easy_install for readline.
Maverick (10.9) has issues with python/numpy/matplotlib you might need to have a custom python build with homebrew that does not use system libs.
