No module named 'netCDF4'

I am currently working with netCDF data in the Spyder IDE, however when I try to import 'Dataset' from the module
from netCDF4 import Dataset
it is giving me the following error: "No module named 'netCDF4'". I already installed the module but I guess it is not in the same environment where I installed spyder. How can I fix this? If it helps solving my question. When I try to install netCDF4 in the spyder console using 'pip install netCDF4' it gives the following error:
"/Applications/Spyder.app/Contents/MacOS/python: No module named pip
Note: you may need to restart the kernel to use updated packages."
I looked up the path of the module: '/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/netCDF4'
and I guess the path for spyder is:
'/Applications/Spyder.app/Contents/MacOS/python'
How can I make sure that they are both located in the same environment?
I tried to look up the issue, however nothing really solved my problem.
Would be glad if anyone could help me out.

ModuleNotFoundError: No module named 'ebooklib'

Hi I'm using ebooklib in python and I'm getting this error
ModuleNotFoundError: No module named 'ebooklib'
I have successfully installed this library and it appears in my pip3 packages list.
I'm importing this in my python file like this
import os
import logging
import sys
import json
import traceback
from ast import literal_eval
from htmlparse import MyHTMLParser
from ebooklib import epub
I don't know what's wrong.

I had the same issue & fixed it by adding:
> export PYTHONPATH="/usr/local/lib/python3.8/site-packages:$PYTHONPATH"
to my .bash_profile file.
To see where your ebooklib is installed to
print(ebooklib.__file__)

How to over come the OS Error in mac while reading pandas

I use Jupyter on my MacBook Pro (macOS Catalina) and when I use pandas to read a CSV file, after the read command, I get an OS error. How do I resolve this?
This is how the error is displayed:
import pandas as pd
r_filenameCSV='/Users/manubharathmurali/Documents/Sacramentorealestatetransactions.csv'
csv_read=pd.read_csv (r_filenameCSV)
csv_read
This is how the error is displayed
Pic 2 of error
After the 3rd line of code OS error is shown.

You are getting this error because Python cannot find the path and therefore you need to change your working directory. You can do this with the Operating system interface in Python.
Change your working directory using os.chdir(path) For more methods with the Python os see the docs Click here to read
import os
import pandas as pd
os.chdir("/Users/manubharathmurali/Documents")
#confirm the path directory
print(os.getcwd())
csv_read = pd.read_csv("Sacramentorealestatetransactions.csv")
print(csv_read)

Python module loading with Spyder

I am new to using Python for machine learning and I am trying to learn ZhuSuan using Spyder.
I have downloaded and installed Zhusuan as descibed here: https://zhusuan.readthedocs.io/en/latest/.
I have also tried installing the additional dependencies required for the examples by following the instructions here: https://github.com/wmyw96/ZhuSuan.
I then try and run an example script (eg https://github.com/thu-ml/zhusuan/blob/master/examples/bayesian_neural_nets/bayesian_nn.py), importing the modules as with the code:
from __future__ import absolute_import
from __future__ import print_function
from __future__ import division
import os
import tensorflow as tf
from six.moves import range, zip
import numpy as np
import zhusuan as zs
from examples import conf
from examples.utils import dataset
However, on execution, I receive the following error:
File "C:/*******/bayesian_nn.py", line **, in <module>
from examples import conf
ModuleNotFoundError: No module named 'examples'
I would be very grateful if anyone could anyone help identify where I have gone wrong with loading or importing the example modules.
Many thanks in advance.

I have solved the problem. The additional dependencies had not installed correctly for some reason. Running a full reinstall fixed the problem, and the program now runs successfully with the original code. Thanks to Carlos for his comment.

ImportError: cannot import name DataFrame

I am using Pandas for the first time and trying to import Pandas, DataFrame and pandas.io.data as such
import pandas as pd
from pandas import DataFrame
import pandas.io.data
I get the error
"ImportError: cannot import name DataFrame"
and
"ImportError: No module named io.data"
I have tried the following to find the source of error on Ubuntu 14.04:
$pip show pandas
-> Version: 0.14.0
Location: /home/new-pc/anaconda/lib/python2.7/site-packages
$$PATH
-> bash: /home/new-pc/anaconda/bin
Not sure where else to look for errors. Thanks for all the inputs.

You must be mixing Python installations, with several python programs/distributions (Anaconda), and maybe python version (2 and 3)
The following commands should not produce any error:
sudo apt-get install python
sudo pip install pandas
python -c'import pandas as pd; from pandas import DataFrame; import pandas.io.data'

It will happen if you call your file pandas.py and try to run it. You should rename the file then.
It will also occur if you save a pandas.py file in the Python directory. Check if you have any files called pandas.py there and rename/move those files to another location.

Try:
from pandas_datareader import data
as shown in the example here

Check if you have saved any file with same names as in pandas libraries, such as saving file name as DataFrame.py. Always avoid naming the program as same as library name check all the location.Once you remove/rename your python script will run without any issue.
