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)
<ipython-input-1-0aa0b027fcb6> in <module>
----> 1 import numpy as np
~\numpy.py in <module>
1 from numpy import*
2
----> 3 arr = array([1,2,3,4])
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 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 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.

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 am attempting run in Jupyter
import pandas as pd
import matplotlib.pyplot as plt # plotting
import numpy as np # dense matrices
from scipy.sparse import csr_matrix # sparse matrices
%matplotlib inline
However when loading the dataset with
wiki = pd.read_csv('people_wiki.csv')
# add id column
wiki['id'] = range(0, len(wiki))
wiki.head(10)
the following error persists
NameError Traceback (most recent call last)
<ipython-input-1-56330c326580> in <module>()
----> 1 wiki = pd.read_csv('people_wiki.csv')
2 # add id column
3 wiki['id'] = range(0, len(wiki))
4 wiki.head(10)
NameError: name 'pd' is not defined
Any suggestions appreciated
Select Restart & Clear Output and run the cells again from the beginning.
I had the same issue, and as Ivan suggested in the comment, this resolved it.
If you came here from a duplicate, notice also that your code needs to contain
import pandas as pd
in the first place. If you are using a notebook like Jupyter and it's already there, or if you just added it, you probably need to re-evaluate the cell, as suggested in the currently top-voted answer by martin-martin.
python version will need 3.6 above, I think you have been use the python 2.7. Please select from top right for your python env version.
Be sure to load / import Pandas first
When stepping through the Anaconda Navigator demo, I found that pressing "play" on the first line before inputting the second line resolved the issue.
I'm trying to plot some graphs using the latest version of Pycharm as a Python IDE.
As an interpreter, I'm using Anaconda with Python 3.4.3-0.
I have installed using conda install the news version of pandas (0.17.0), seaborn (0.6.0), numpy (1.10.1), matplotlib (1.4.3), ipython (4.0.1)
Inside the nesarc_pds.csv I have this:
IDNUM,S1Q2I
39191,1
39787,1
40082,1
40189,1
40226,1
40637,1
41306,1
41627,1
41710,1
42113,1
42120,1
42720,1
42909,1

22476,9
24207,9
25762,9
29045,9
29731,9
So, that being said, this is my code:
import pandas as pd
import numpy
import seaborn as snb
import matplotlib.pyplot as plt
data = pd.read_csv("nesarc_pds.csv", low_memory=False)
#converting variable to numeric
pd.to_numeric(data["S1Q2I"], errors='coerce')
#setting a new dataset...
sub1=data[(data["S1Q2I"]==1) & (data["S3BQ1A5"]==1)]
sub2 = sub1.copy()
#setting the missing data 9 = unknown into NaN
sub2["S1Q2I"] = sub2["S1Q2I"].replace(9, numpy.nan)
#setting date to categorical type
sub2["S1Q2I"] = sub2["S1Q2I"].astype('category')
#plotting
snb.countplot(x="S1Q2I", data=sub2)
plt.xlabel("blablabla")
plt.title("lalala")
And then.....this is the error:
Traceback (most recent call last):

Any help would be really nice. I pretty much exhausted my intelligence trying to understand how to solve this.
I am trying to resample 1 minute based data to day. I have tried the following code on IPython
import pandas as pd
import numpy as np
from pandas import Series, DataFrame, Panel
import matplotlib.pyplot as plt
%matplotlib inline
data = pd.read_csv("DATALOG_22_01_2014.csv",\
names = ['DATE','TIME','HUM1','TMP1','HUM2','TMP2','HUM3','TMP3','WS','WD'])
data.set_index(['DATE','TIME'])
data.resample('D',how=mean)
But I got the following error
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-75-aa63b6b16877> in <module>()
----> 1 data.resample('D', how=mean)
NameError: name 'mean' is not defined
Could you help me?
Thank you
Hugo
Try
data.resample('D', how='mean')
instead. Right now you're asking Python to pass the mean object to the resample method as the how argument, but you don't have one defined.
