Is there any way to force ipython to interpret utf-8 symbols?
string,utf-8,ipython,literals,diacritics
Your problem is that you are getting two characters for the 'ó' character instead of one. Therefore, try to change it to unicode first so that every character has the same length as follows: def remove_accent(n): n_unicode=unicode(n,"UTF-8") listn = list(n_unicode) for i in range(len(listn)): if listn[i] == u'ó': listn[i] =...

How to update python 2.7 in HDP 2.2 using with Spark and Python
python,python-2.7,hadoop,ipython
Python is not integrated with the Hadoop system. Python 2.6.6 is the default version for Centos 6.5 / RHEL 6. You should under no circumstances attempt to uninstall/update the default version, because it has system dependencies. What you can do is to install a newer version of python as...
Adding multiple rows in an existing dataframe

Returning to host code in pyCUDA after asynchronous kernel launch
python,python-2.7,cuda,ipython,pycuda
I figured this out, so am posting my solution. Even though asynchronous memcpy's are non-blocking, I discovered that doing a memcpy using the same stream as a running kernel does not work. My solution was to create another stream: strm2 = driver.Stream() and then change d_inShot like so: d_inShot.set_async(h_inShot.astype(np.uint16), stream...

How to write an ipython alias which executes in python instead of shell?

How to import modules in IPython Clusters

It seems that with dview.sync_imports() is being run someplace other than your IPython Notebook environment and is therefore relying a different PYTHONPATH.

Troubles after updating ipython (%matplotlib nbagg)
python,matplotlib,ipython,ipython-notebook,jupyter
I guess this issue is caused by a too old version of matplotlib. Using %matplotlib nbagg with ipython>=3.0 requires matplotlib>=1.4.3 (Note that %matplotlib notebook and %matplotlib nbagg are now synonyms). Updating matplotlib via pip install --upgrade matplotlib will probably fix this issue. See also my issue-7797 on github. Thanks to...

How to use groupby in Pandas to compute columns
To get to your desired table, you basically just have to unstack gpm to move Bracket and Win into the columns: unstacked = gpm.unstack(['Bracket', 'Win']) Then you can use a simple str.join to create strings out of the column levels: new_cols = unstacked.columns.to_series().map( lambda t: '_'.join(str(e) for e in t))...

Why sorted list detection does not work in this situation?
I was able to reproduce a similar problem on my machine. However, after digging, it occurred that the all function was not the built-in function but came from numpy (all.__module__ == 'numpy.core.fromnumeric'). The problem is that you are creating a generator rather than a list. For example: all(x>5 for x...
Why is it possible to call functions using slashes in iPython?
python,ipython,ipython-notebook
This is simply one of the features of ipython. It exists to make it possible to call functions without using the parenthesis. Starting your line with / tells it to treat the first word as a function name, add parenthesis to it, and treat any following words or symbols as...

IPython history is stored in a SQLite database located in the profile directory. By default: ~/.ipython/profile_default/history.sqlite Older versions (1.x) stored profile data in ~/.config/ipython, at least on platforms conforming to XDG basedir specs (i.e. most Linux distributions). Anyway, you can locate the profile directory with: $ ipython locate profile default...

How do I change the kernel/python version for iPython?

How to inspect generators in the repl/ipython in Python3
python,python-3.x,ipython,python-3.4
Your idea of previewing or rewinding a generator is not possible in the general case. That's because generators can have side effects, which you'd either get earlier than expected (when you preview), or get multiple times (before and after rewinding). Consider the following generator, for example: def foo_gen(): print("start") yield...

How to access a variable in IPython from a program executed by %run
You could first check for the variable's existence, and only assign to it if it doesn't exist. Example: if __name__=="__main__": if not "foo" in globals() foo = expensiveDataProcessClass(filepath) However, this won't actually work (in the sense of saving a foo assignment).
