ModuleNotFoundError: Pyramid

I'm trying to import these libraries:
from math import sqrt
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from statsmodels.tsa.arima_model import ARIMA
from sklearn.metrics import mean_absolute_error, mean_squared_error
from pyramid.arima import auto_arima
from statsmodels.tsa.stattools import adfuller
But this error is coming again and again
ModuleNotFoundError: No module named 'pyramid'
I have tried pip install pyramid-arima but it's also throwing me so many errors in cmd.
Can anyone suggest to me what I can do to resolve this problem?

try
pip install pmdarima
pmdarima is the official new name for pyramid.arima.

Try to install pmdarima by using pip:
pip install pmdarima
I also needed to modify my python script to use:
from pmdarima.arima import auto_arima

modulenotfounderror no module named 'modin'

I have created a virtual environment with following syntax in the windows terminal:
conda create --prefix ./modinenv python=3.6 numpy
conda activate e:\modin\modinenv
pip install modin[dask]
jupyter notebook
In a new python file, when i executed this following command:
import modin.pandas as pd
it gives me an error: modulenotfounderror no module named 'modin'
I searched many forum, but got no workable response to this.
I even tried following before import statement:
import os
os.environ["MODIN_ENGINE"] = "dask" # Modin will use Dask
import modin.pandas as pd
This also does not work here. So any help in this regard is appreciated.
Thanks

I have exactly the same environment setting as you.
import os
import modin.pandas as pd
os.environ["MODIN_ENGINE"] = "dask"
Try following:
It seems that your Modin may not install properly, so please try pip install -U modin according to Modin documentation
pip3 install 'modin[dask]'

Module Not Found Error: No module named 'chart_studio'

I run !pip install chart_studio in jupyter notebook.
Then when running this code:
import numpy as np
import pandas as pd
import cufflinks as cf
import chart_studio.plotly as py
from chart_studio.plotly import iplot
import plotly.graph_objects as go
chart_studio.tools.set_credentials_file(username=xx, api_key = xxx)
I get back:
No module named 'chart_studio'
I've tried syntax corrections but no joy. Any suggestions?

Just pip install chart_studio in the current environment

Use conda for the installation:
conda install -c plotly chart-studio

Yes it worked with:
pip install chart-studio

import chart_studio.plotly as py
In the line above you have imported chart_studio as py. So,
chart_studio.tools.set_credentials_file(username=xx, api_key = xxx)
in this line you need call through the alias as
py.tools.set_credentials()
Else, you can just import chart_studio.plotly and use it directly.
Please comment if you have any doubts.

The module chart_studio is no longer a module of the plotly package. You need to install chart-studio package
https://pypi.org/project/chart-studio/

!pip install chart_studio
if you are doing it on google colab

Error when importing RegularGridInterpolator from scipy.interpolate

I have a problem when trying to run a code for a course at the university. The main file BASEchange.py tries to import 2 modules called "NODE" and "MESHMODEL". "MESHMODEL", in turn, imports RegularGridInterpolator from scipy.interpolate .
When I run the program in the mac terminal, using "python BASEchange.py -h", I get the following error:
ImportError: cannot import name RegularGridInterpolator
I have scipy intalled via pip.
Here are the first lines form meshModel.py:
import sys, os, platform, subprocess, stat, re, abc, math, linecache, shutil
import numpy as np
from scipy.interpolate import RegularGridInterpolator
from scipy import interpolate
from scipy.sparse import csc_matrix, lil_matrix, tril, find
from scipy.sparse.csgraph import reverse_cuthill_mckee
Thanks in advance!

You probably have the wrong version of scipy. Note that RegularGridInterpolator are only supported from version 0.14.
Do the following.
upgrade your pip
for Python 3:
python3 -m pip install --upgrade pip
for Python 2:
python2 -m pip install --upgrade pip
Then Follow the commands from here to install scipy:
python -m pip install --user scipy

ImportError: No module named pandas_datareader

I am trying to use the pandas data reader library.
I initially tried import pandas.io.data but this threw up an import error, stating I should be using
from pandas_datareader import data, wb
instead. Upon trying this I was greeted with
ImportError: No module named pandas_datareader
I have had a look around and have tried...
"pip install pandas_datareader"
"pip install python_datareader"
"pip install pandas-datareader"
Any help would be greatly appreciated

run this command pip install pandas-datareader and for more info documentation is here
