I am attempting to import the scipy module into my code in order to use the KDTree function. This is done on replit.
I wrote "from scipy import spatial", and on running it errors saying "no module named 'scipy'".
I have tried importing various things from scipy, but it says that scipy doesn't exist.
How can I fix this?
scipy is not a built-in but it is an external python package.
For this reason you have to install it before to use it.
You can use the following command in your terminal:
pip install scipy
There also other way to install it, check the documentation for more details.
My suggestion (but it is not mandatory) is to use a virtualenv.
Here you can find a tutorial on how to create it and how to use it.

I tried to import numpy but I received a ModuleNotFoundError: No module named 'numpy' error. Someone told me it could be because I didn't have numpy installed, but I already did.
upon installing numpy I got Requirement already satisfied: numpy in ./opt/anaconda3/lib/python3.8/site-packages.
which python returns /Users/MacBook/opt/anaconda3/bin/python. I am new at this, but I'm guessing the reason I got that error was because the files aren't in the same place? If so, how do I move it to the right place?
side note: I have a similar issue with matplotlib and this is running on VS code if that helps. Also I use spyder and I don't get the numpy nor the matplotlib error over there, but the error seems to be on VS code
Try uninstalling numpy and re-installing. You also try re-install anaconda. I had this same issue and that fixed it.
Anaconda installs its own conda environment to run python. Probably VS Code can't access. Try this command;
python -mpip install numpy
If your python file named numpy.py, you can get this error too.
If doesn't work maybe you can try to change the environment to Anaconda environment.

I'm trying to import https://github.com/chrisconlan/algorithmic-trading-with-python in my code. I've never imported anything from GitHub before and have looked at various other questions that have been asked on Stack Overflow regarding this problem but it just doesn't work. When I try to run the 'portfolio.py' code for example I keep getting a ModuleNotFound error for 'pypm'. What exactly is the correct way to import such a module or the whole GitHub directory?
I'm working with Visual Studio Code on Windows.
You will need to pip install the module. In your case the command you would need to run is python -m pip install -U git+https://github.com/chrisconlan/algorithmic-trading-with-python. Once you have done that you need to find the name of the module. You can do this with pip list. Find the name of the module you just installed.
Then you just stick import <module name> at the top of your code with the rest of your imports.
What i used to do in this is to clone the repository on the folder where are installed the python's packages. This is useful when you do not want to use the pip cmd tool, keeping the pip's cache memory under control.
The Current problem I am looking into is described below:
My computer is Win10, I installed only one anaconda 3.5.3 on it. Using where python there is only one python in my computer.
I downloaded a rpy2python wheel file from the uefi website, and install that using pip install.
When I import rpy2 in C disk, it is already fine, import rpy2,import rpy2.robjects are all OK.
But when I import rpy2 in my own project, I can only first import rpy2, when I import rpy2.robjects,the program says can not find rpy2 module.
Finally I found the problem is that in my project, I occasionaly established an rpy2.py file, when I first import rpy2, it where automatically create an rpy2.pycache folder, secondly when I import rpy2.robjects, Of Course the computer can not find an rpy2.robjects.
Just Keep a track of my problem.
You'll want to check the Python documentation about import rules for modules. By default, having a file called rpy2.py in the working directory for your Python code will cause import rpy2 to find this one rather that the rpy2 package.
The easiest fix is probably to rename your module rpy2.py into something else.
I was following the tutorial of programming the Monty hall problem in python and all these errors came up and I've looked through the tutorial multiple times and still don't know what I've done wrong.
This is where all these errors came up in the same order
Unable to import 'numpy'pylint(import-error) Unable to import 'matplotlib.pyplot'pylint(import-error) Unused variable 'Simulate'pylint(unused-variable)][1]
Here is where these errors came up in the same order
Unused variable 'TakeTurn'pylint(unused-variable) Unused variable 'DisplayResults'pylint(unused-variable)][2]
And finally this error Instance of 'Simulation' has no 'Simulate']3
Be sure to install those packages with pip before importing them. If not installed python would look for the package a not find it. Then you get errors.
Check if those packages are installed on your machine.
Like pip install matplotlib
I have recently installed python 2.17.14 to use a package which I installed in the command prompt with:
python -m pip install packageName
However, whenever I try to use it with a script provided by the package authors, I get Import Errors:
ImportError: cannot import X from YX
ImportError: attempted relative import with no known parent package.
I don't know what I'm doing wrong, as I am really new to Python. Does anyone have any ideas?
The package is called neurodesign and I downloaded the try out script from the official website "neuropowertools.org"
Best,
Max
In case anyone (who is also new to python^^) fails ridiculously at this task as well: I had to manually install all the modules used within this package for it to work as they weren't installed automatically.
