How do I fix This error: DistributionNotFound: The 'ptyprocess>=0.5' distribution was not found and is required by pexpect

Hi I have difficulties in fitting data using Fitter module in Python and I don't understand the error as I am quite new to Python. The following code below is what I done so far in order to get the summary.
import fitter
f=fitter.Fitter(data=data["ROAS"], distributions= ['gamma'])
f.fit()
f.summary()
The error I get is:
DistributionNotFound Traceback (most recent call last)

771 to_activate.append(dist)

Please can someone help me to run the code without the error, thanks.

I had the same problem. I installed the "ptyprocess" library and now it works.

Python ipwhois ASN Registry Error

I am using ipwhois for the first time. Running the basic usage example with a Google IP address works:
from ipwhois import IPWhois
obj = IPWhois('74.125.225.229')
results = obj.lookup_rdap(depth=1)
Any other IP address results in this error:

I attempted to switch the lookup method to ARIN with bootstrap=True to no avail. How do I remedy this error?

Using Sacred Module with iPython

I am trying to set up sacred for Python and I am going through the tutorial. I was able to set up sacred using pip install sacred with no issues. I am having trouble running the basic code:
from sacred import Experiment
ex = Experiment("hello_world")
Running this code returns the a ValueError:

---> 63 .format(filename))
64
65 mainfile = get_py_file_if_possible(os.path.abspath(filename))
ValueError: invalid filename or file not found "None"
I am not sure why this error is returning. The documentation does not say anything about setting up an Experiment file prior to running the code. Any help would be greatly appreciated!

The traceback given indicates that the constructor for Experiment searches its namespace to find the file in which its defined.
Thus, to make the example work, place the example code into a file and run that file directly.
If you are using ipython, then you could always try using the %%python command, which will effectively capture the code you give it into a file before running it (in a separate python process).

According to the docs, if you're in IPython/Jupyter, you can allow the Experiment to run in a non-reproducible interactive environment:
ex = Experiment('jupyter_ex', interactive=True)
https://sacred.readthedocs.io/en/latest/experiment.html#run-the-experiment

The docs say it nicely (TL;DR: sacred checks this for you and fails in order to warn you)
Warning
By default, Sacred experiments will fail if run in an interactive
environment like a REPL or a Jupyter Notebook. This is an intended
security measure since in these environments reproducibility cannot be
ensured. If needed, this safeguard can be deactivated by passing
interactive=True to the experiment like this:
ex = Experiment('jupyter_ex', interactive=True)

Setting interactive=True doesn't work if you run the notebook as a script through ipython.

Sympy, plotting geometric entities yields either ImportError: no module named 'plot' or AttributeError: 'Circle' object has no attribute 'is_3D'

Setup: Using Python 3.4.1 from the Anaconda 2.1.0 64-bit installer for Windows 8.1
Using IPython 2.2.0 console
As usual with the Anaconda installer, I have matplotlib 1.4.0 that comes with it.
And I updated from the default sympy on Anaconda to sympy 0.7.6
Problem: I am trying to plot geometric entities as discussed in the sympy documentation http://docs.sympy.org/latest/modules/plotting.html#plot-geom in at least three ways, all yielding errors.
First try using the 'older' PygletPlot, the module being used in the above reference documentation:
In [1]: from sympy.plotting.pygletplot import PygletPlot as Plot
In [2]: from sympy import Point, Circle
In [3]: c1 = Circle(Point(1, 0), 3)
In [4]: p = Plot(axes='label_axes=True')
---------------------------------------------------------------------------

138

141
ImportError: No module named 'plot'
In [5]: Plot(c1)
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-5-4edba1117b3a> in <module>()
----> 1 Plot(c1)

140 return plot.PygletPlot(*args, **kwargs)
141

138
--> 139 import plot
140 return plot.PygletPlot(*args, **kwargs)
141
ImportError: No module named 'plot'
Second try using the 'newer' plotting module, which keeps being recommended in answers for most plotting problems with sympy:
In [1]: from sympy.plotting.plot import Plot
In [2]: from sympy import Point, Circle
In [3]: c1 = Circle(Point(1, 0), 3)
In [4]: p = Plot(c1)
In [5]: p.show()

864 self.matplotlib = import_module('matplotlib',
865 __import__kwargs={'fromlist': ['pyplot', 'cm', 'collections']},

AttributeError: 'Circle' object has no attribute 'is_3D'
In [6]: Plot(c1)
Out[6]: <sympy.plotting.plot.Plot at 0x6f74ac8>
Third try using the plot() function which the sympy documentation recommends for interactive work:
In [1]: from sympy import plot
In [2]: from sympy import Point, Circle
In [3]: c1 = Circle(Point(1, 0), 3)
In [4]: plot(c1)

Thanks for your attention. This is my first time writing a question so I hope I have provided enough information.

How do I use Python to auto generate a simple powerpoint example?

I'm trying to reproduce the result of the example file provided by Prof. Zhao using Enthought Canopy:
http://www.shengdongzhao.com/shen_blog/how-to-automatically-create-powerpoint-slides-using-python/
I seem to be having the same problem that others are having (and seem to still be having) which you can see in the comments below the linked blog post. I realize prof. Zhao mentions that the error could be due to the environment not being set correctly. I thought it might have something to do with environment variables not being pointed to correctly. I tried the the first answer at the following but it seems like it prevents canopy from even opening (doing something wrong I am)
How to add to the pythonpath in windows 7?
So what I'm left doing is: I open his scripts in Canopy and then I run MSO.py and then MSPPT.py and then MSPPTUtil.py. Then, when I run CreateSlideExamples.py (with photo.JPG's directory updated) I only get a single power-point slide with the table
The console is littered with the following list of errors:
