I have code that gets the parent directory of the current file, this works when running in VScode but when I transfer the code to a Jupyter notebook it stops working.
import pandas as pd
import os
from pathlib import Path
import matplotlib.pyplot as plt
cur_path = Path(os.path.dirname(__file__))
root_path = cur_path.parent.absolute()
train_data_path = '{}\\data\\train_codified.csv'.format(str(root_path))
test_data_path = '{}\\data\\test_codified.csv'.format(str(root_path))
this returns the following error:
NameError Traceback (most recent call last)
Input In [1], in <cell line: 7>()
3 from pathlib import Path
4 import matplotlib.pyplot as plt
----> 7 cur_path = Path(os.path.dirname(__file__))
8 root_path = cur_path.parent.absolute()
10 train_data_path = '{}\\data\\train_codified.csv'.format(str(root_path))
NameError: name '__file__' is not defined
why does the code not function in a notebook?
I have replaced
cur_path = Path(os.path.dirname(__file__))
with
cur_path = Path(os.getcwd())
this works so my problem is solved. I am still not sure why __file__ is not defined so if anyone knows please let me know.

The code I'm working on is with a dataset which contains like numbers in alphabets, So I want to convert it into string to feed to into a Multivariate Model.
!pip install word2number
import pandas as pd
import math
from sklearn import linear_model
import word2number as w2n
print("sucessfully imported all the libraries")
df = pd.read_csv('hiring.csv')
df
print(w2n.word_to_num('one'))
This is my code and the error I'm getting is
AttributeError Traceback (most recent call last)
c:\Users\tanus\Desktop\Machine Learning\Regression\Multivariate Regression\Multivariate_Regression.ipynb Cell 2 in <cell line: 4>()
1 df = pd.read_csv('hiring.csv')
2 df
----> 4 print(w2n.word_to_num('one'))
AttributeError: module 'word2number' has no attribute 'word_to_num'
you have to import w2n module from word2number
from word2number import w2n
print(w2n.word_to_num('two point three'))
You are directly using word_to_num from the module i assume.
Please check the import statement.
The error is possible if you use below import.
import word2number as w2n
Hope this helps
from ggplot import mtcars
While importing mtcars dataset from ggplot on jupyter notebook i got this error
My system is windows 10 and I've already reinstalled and upgraded pandas (also used --user in installation command)but it didn't work out as well. Is there any other way to get rid of this error?
\Anaconda3\lib\site-packages\ggplot\stats\smoothers.py in
2 unicode_literals)
3 import numpy as np
----> 4 from pandas.lib import Timestamp
5 import pandas as pd
6 import statsmodels.api as sm
ModuleNotFoundError: No module named 'pandas.lib'
I Just tried out a way. I hope this works out for others as well. I changed from this
from pandas.lib import Timestamp
to this
from pandas._libs import Timestamp
as the path of the module is saved in path C:\Users\HP\Anaconda3\Lib\site-packages\pandas-libs
is _libs
Also, I changed from
date_types = (
pd.tslib.Timestamp,
pd.DatetimeIndex,
pd.Period,
pd.PeriodIndex,
datetime.datetime,
datetime.time
)
to this
date_types = (
pd._tslib.Timestamp,
pd.DatetimeIndex,
pd.Period,
pd.PeriodIndex,
datetime.datetime,
datetime.time
)
Before that, I went on this path "C:\Users\HP\Anaconda3\Lib\site-packages\ggplot\util.py" to make the same changes in util.py for date_types. This helped me out to get rid of the error I mentioned in my question.
I am new to Python and I am trying to start CNN for one project. I mounted the gdrive and I am trying to download images from the gdrive directory. After, I am trying to count the images that I have in that directory. Here is my code:
import pathlib
dataset_dir = "content/drive/My Drive/Species_Samples"
data_dir = tf.keras.utils.get_file('Species_Samples', origin=dataset_dir, untar=True)
data_dir = pathlib.Path(data_dir)
image_count = len(list(data_dir('*/*.png')))
print(image_count)
However, I get the following error.
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-78-e5d9409807d9> in <module>()
----> 1 image_count = len(list(data_dir('*/*.png')))
2 print(image_count)
TypeError: 'PosixPath' object is not callable
Can you help, please?
After suggestion, my code looks like this:
import pathlib
data_dir = pathlib.Path("content/drive/My Drive/Species_Samples/")
count = len(list(data_dir.rglob("*.png")))
print(count)
You are trying to glob files you need to use one of the glob methods that pathlib has:
import pathlib
data_dir = pathlib.Path("/path/to/dir/")
count = len(list(data_dir.rglob("*.png")))
In this case .rglob is a recursive glob.
I've some code like:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
data = pd.read_csv('StudentsPerformance.csv')
#print(data.isnull().sum()) // checking if there are some missing values or not
#print(data.dtypes)checking datatypes of the dataset
# ANALYSİS VALUES OF THE COLUMN'S
"""print(data['gender'].value_counts())
print(data['parental level of education'].value_counts())
print(data['race/ethnicity'].value_counts())
print(data['lunch'].value_counts())
print(data['test preparation course'].value_counts())"""
# Adding column total and average to the dataset
data['total'] = data['math score'] + data['reading score'] + data['writing score']
data['average'] = data ['total'] / 3
sns.distplot(data['average'])
I would like to see distplot of average for visualization but I run the program that gives me an error like
Traceback (most recent call last): File
"C:/Users/usersample/PycharmProjects/untitled1/sample.py", line 22, in
sns.distplot(data['average']) AttributeError: module 'seaborn' has no attribute 'distplot'
I've tried to reinstall and install seaborn and upgrade the seaborn to 0.9.0 but it doesn't work.

this might be due to removal of paths in environment variables section. Try considering to add your IDE scripts and python folder. I am using pycharm IDE, and did the same and its working fine.
I am trying to import and read all images in a folder. However, when I have more than 5 images, cv2.imread returns none for the 6th image. I have tried using different file names, different files, etc, but I can't get it to work.
import cv2
import numpy as np
import matplotlib.pyplot as plt
from tkinter import filedialog
import os
from mpl_toolkits.mplot3d import Axes3D
global scan_dir
scan_dir = filedialog.askdirectory()
print(scan_dir)
x=os.listdir(scan_dir)
img={}
print(x)
for i in range(0,len(x)):
print(i)
img[i] = cv2.imread(x[i], cv2.IMREAD_GRAYSCALE)
indices[i] = np.where(img[i]<100)
I get the following error...(None is the return of print(img[i] on 6th iteration of the loop)
None
Traceback (most recent call last):
File "C:\CodeRepository\US-3D\GettingCloser.py", line 55, in <module>
indices[i] = np.where(img[i]<100)
TypeError: '<' not supported between instances of 'NoneType' and 'int'
I have the same problem if I try this
global scan_dir
scan_dir = filedialog.askdirectory()
print(scan_dir)
x=os.listdir(scan_dir)
img = cv2.imread(x[5], cv2.IMREAD_GRAYSCALE)
It will return that img is None. This is true for anything beyond the 5th image.
Must be something wrong with the file. dicts are an unordered Data structure. Should not give error always on 5th iteration. However, I have made the changes which will not throw the error. But you need to debug that image
for i in range(0,len(x)):
print(i)
img[i] = cv2.imread(x[i], cv2.IMREAD_GRAYSCALE)
if img[i]:
indices[i] = np.where(img[i]<100)
