I get an errr when using scipy.stats. in a script after importing scipy.
AttributeError: 'module' object has no attribute 'stats'
Within script editor I can click on stats after typing scipy. from the pulldown menu,
within python console I can not select python.stats from the pulldown menu, it's not there.
I'm using pandas 2.7 and SciPy 0.13.0
Why is that?
Any known issues?
expanding on my comment (to have a listed answer).
Scipy, as many other large packages, doesn't import all modules automatically. If we want to use the subpackages of scipy, then we need to import them directly.
However, some scipy subpackages load other scipy subpackages, so for example importing scipy.stats also imports a large number of the other packages. But I never rely on this to have the subpackage available in the namespace.
In many packages that use scipy, the preferred pattern is to import the subpackages to have them available by their names, for example:
>>> from scipy import stats, optimize, interpolate
>>> import scipy
>>> scipy.stats
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'stats'
>>> scipy.optimize
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'optimize'
>>> import scipy.stats
>>> scipy.optimize
<module 'scipy.optimize' from 'C:\Python26\lib\site-packages\scipy\optimize\__init__.pyc'>
This is expected. Most of the subpackages are not imported when you just do import scipy. There are a lot of them, with a lot of heavy extension modules that take time to load. You should always explicitly import the subpackages that you want to use.
https://github.com/scipy/scipy/issues/13618
if you import scipy alone like this:
import scipy
then you use:
scipy.stats
You will get:
AttributeError: module 'scipy' has no attribute 'stats'
You have to import like this:
import scipy.stats
or
import scipy
import stats

I was just getting started with PyCharm and python for statistics.
And I got this error:
ImportError: cannot import name 'int' from 'numpy' (/home/tetiana/.local/lib/python3.8/site-packages/numpy/init.py)
Full traceback looks like this:
Traceback (most recent call last):

ImportError: cannot import name 'int' from 'numpy' (/home/tetiana/.local/lib/python3.8/site-packages/numpy/init.py)
Process finished with exit code 1
How can I fix it?
Here is my code:
from scipy import stats
import pandas as pd
state = pd.read_csv('state_murder_rate_test_table.csv')
state['Population'].mean()
stats.trim_mean(state['Population'], 0.1)
state['Population'].median()
I checked whether the Python versions in os and in the project match and they are. I have python 3.8.10 and my os is Ubuntu 20.04
Referring to the current numpy documentation, there exists no type called numpy.int that you can import. I believe that the type you wanna import is numpy.integer or numpy.int_.
The code you provided does not have any statement like: from numpy import int. If you could provide a full traceback error, it'll be easier to see where the error stems from.
I hope this answer will be somewhat useful.

I have been trying to recreate the Keras-bidaf model in my python notebook and running this code in python from bidaf. models import BidirectionalAttentionFlow which keeps giving me the above error and saying Adadelta can't be imported from Keras. I have tried so many options to solve it but no luck.
I am stuck here. Any suggestions and ideas are highly appreciated.
When I import numpy and pandas in jupyter it gives error same in spider but in spider works after starting new kernel.
import numpy as np
NameError Traceback (most recent call last)

----> 1 import numpy as np

NameError: name 'array' is not defined
this is showing "NameError" which is due to the
arr=array([1,2,3,4])
you should try something like this
arr=np.array([1,2,3,4])
I found the error. It was a very bad mistake my c files have program numpy.py so while importing numpy python was accessing that file not the numpy module. So i deleted that and everything worked fine.
Try this:
arr=np.array([1,2,3,4])
As you are using numpy as np, to create an array the following syntax is needed:
arr=np.array([1,2,3])
I try to do the following

I look up the documentation and it seems these libraries existed since .12 . I dont know what the issue is, but im sure its something simple im not seeing.

General recommendations for importing functions from scipy .
On a side note, best avoid star imports. These from scipy import *, from numpy import * are not recommended and not needed here. Same for import scipy as s.
I am trying to use matplotlib for real-time analysis from ECG-signals, but the problem starts even before.
I use the PyCharm IDE, currently working with Python 3.3 and my os is Windows 8.1.
For Matplotlib I downloaded matplotlib and the dependencies (numpy, six, dateutil, pyparsing, pytz) from here (the versions for Python 3.3): http://www.lfd.uci.edu/~gohlke/pythonlibs/ and installed it in the Python33 folder.
Now if I try:
from matplotlib.pyplot import plot, show
plot(range(10))
show()
or:
import pylab
from pylab import *
xAchse=pylab.arange(0,100,1)
yAchse=pylab.array([0]*100)
fig = pylab.figure(1)
ax = fig.add_subplot(111)
ax.grid(True)
ax.set_title("Realtime Waveform Plot")
ax.set_xlabel("Time")
ax.set_ylabel("Amplitude")
ax.axis([0,100,-1.5,1.5])
line1=ax.plot(xAchse,yAchse,'-')
manager = pylab.get_current_fig_manager()
values=[]
values = [0 for x in range(100)]
Ta=0.01
fa=1.0/Ta
fcos=3.5
Konstant=cos(2*pi*fcos*Ta)
T0=1.0
T1=Konstant
def SinwaveformGenerator(arg):
global values,T1,Konstant,T0
#ohmegaCos=arccos(T1)/Ta
#print "fcos=", ohmegaCos/(2*pi), "Hz"
Tnext=((Konstant*T1)*2)-T0
if len(values)%100>70:
values.append(random()*2-1)
else:
values.append(Tnext)
T0=T1
T1=Tnext
def RealtimePloter(arg):
global values
CurrentXAxis=pylab.arange(len(values)-100,len(values),1)
line1[0].set_data(CurrentXAxis,pylab.array(values[-100:]))
ax.axis([CurrentXAxis.min(),CurrentXAxis.max(),-1.5,1.5])
manager.canvas.draw()
#manager.show()
timer = fig.canvas.new_timer(interval=20)
timer.add_callback(RealtimePloter, ())
timer2 = fig.canvas.new_timer(interval=20)
timer2.add_callback(SinwaveformGenerator, ())
timer.start()
timer2.start()
pylab.show()
For a smal test, I get two different Error's. For the first one it is the following:
Traceback (most recent call last):
File "<frozen importlib._bootstrap>", line 1519, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute __path__
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/Users/Timo/PycharmProjects/GUI_test/matplotlib.py", line 1, in <module>
from matplotlib.pyplot import plot, show
File "C:\Users\Timo\PycharmProjects\GUI_test\matplotlib.py", line 1, in <module>
from matplotlib.pyplot import plot, show
ImportError: No module named 'matplotlib.pyplot'; matplotlib is not a package
And for the second bigger example it is this:
Traceback (most recent call last):
File "C:/Users/Timo/PycharmProjects/GUI_test/matplotlib.py", line 1, in <module>
import pylab
File "C:\Python33\lib\site-packages\pylab.py", line 1, in <module>
from matplotlib.pylab import *
File "C:\Users\Timo\PycharmProjects\GUI_test\matplotlib.py", line 4, in <module>
xAchse=pylab.arange(0,100,1)
AttributeError: 'module' object has no attribute 'arange'
Afterwards I changed the imports to the ones Pycharm wanted me to use. from matplotlib import pylab but this only resulted in an ImportError. cannot import pylab
The funny thing is, if I run these small tests in the Python Console it works just fine, so my guess is that it has something to do with PyCharm...
I also tried to add the exact path from the matplotlib to the Path variable but that resulted in another Error.
Your current project folder C:/Users/Timo/PycharmProjects/GUI_test/matplotlib.py contains matplotlib.py which causes this issue. Change the filename to anything else, which is not a name of a python package.
