I am trying to use a module from github called ffn and have downloaded it to my desktop. I am using Jupyter notebook for Python and was told i need to insert this code:
import sys
sys.path.insert(0, r"C:\Users\...\Desktop\ffn-master\ffn\_core_.py")
import ffn
..in order to use this code.
However when i run the subsequent lines of code that call functions from here I still get the error:
C:\ProgramData\Anaconda3\lib\site-packages\ffn\core.py:2054:
RuntimeWarning: invalid value encountered in minimum
negative_returns = np.minimum(returns, 0.)
I restarted the kernel and everything but still get the same error.
Can anyone help?
"The desktop module has the fixes that the installed module in the anaconda path does not." - It seems like you still have the original module installed in the anaconda library.
try running
conda uninstall ffn
and then include the entire library in the path in you notebook with
sys.path.append(os.path.abspath(r"C:\Users\...\Desktop\ffn-master\ffn\")

I have several imports in my current code:
from flask import Flask
import datetime as dt
import numpy as np
import pandas as pd
When I run this in VSCODE I am getting this error:
However, running this in jupyter notebook has no problems. When I looked online it said to use python interpreter but when I go to do that I get this error:
And another error:
Anaconda prompt says modules/packages are installed but when I run pip install in default windows terminal it says pip has no module:
Delete and reinstall Python extensions according to the same problem on github.
The second problem is related to the location of your Python interpreter. You need to choose the correct interpreter. I still recommend using one Python version in one environment. You can use other Python versions in virtual environment, so it won't lead to confusion.
Currently I am working on a project with Jupyter Notebook in which I need to run a matlab script (.m) which includes a function that provides me with data which i try to solve with a tensorflow model afterwards. I can set up an environment that runs the matlab code an gives me the data and I can set up an environment that does the tensorflow thing but my problem is I can`t do it in the same environment.
Here is the setup and the problems. I am using matlab.engine which I installed like described here: https://de.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html
To run my Jupyter Notebook I first navigate to the location where my python.exe and the matlab files are lying ("C:\Users\Philipp\AppData\Local\Programs\Python\Python37-32\Scripts"). If I try to run pip install tensorflow (in Anaconda Prompt) I got a lot of different errors like the following. Conda install works but even when it is installed i can`t import it.
ImportError: No module named 'tensorflow.core' or
ERROR: Could not find a version that satisfies the requirement tensorflow or just No module named 'tensorflow'
I searched for all those problems but nothing helped me. I think this has something to do with the directory I am working in and I know it is bad but I have no idea how to change that. The error also occurs in different environments.
Have you tried running !pip install tensorflow directly in Jupyter Notebook? It's a temporary workaround, but I am having the same problems and this one helped. Remember to comment it out after installation, so you wont re-run it by accident.
I found a solution to my problem. For this I needed a Jupyter Notebook and an external .py script that I design as a Flask. I can luckily run those in different environments. I past and request the data from the server by using "get" and "post".
If someone still has another idea to do all this in one JN, I would still be happy about answers.
I'm tyring to import wolfamalpha into my code but it gives a error saying:
ModuleNotFoundError: No module named 'wolframalpha'
I tried installing it with pip install wolframalpha, but it still doesn't work.
Here is my code:
import wolframalpha
client = wolframalpha.Client('*************')
When you run your python file, are you sure that you are using the correct python interpreter that you performed the pip install wolframalpha to? It sounds like you may have multiple versions of python on your machine and there is a mismatch. If you are using VSCode, it is easy to see which interpreter is running on the bottom of the screen, which may help you debug the issue.
I'm running a code on deep learning, which uses the opencv module, by running python main.py (contains import cv2 statement), but always get the error 'ImportError: dynamic module does not define module export function (PyInit_cv2)'.
I've tried to reinstall my anaconda and create new virtual environments, but all got the same result. This problem really confuses me a lot and I've googled for many related problems, none of them works. I think the problem is something related to the environment and has nothing to do with the code, because I got the same result by simply run import cv2 in python prompt. The more confusing thing is that, even after I remove the opencv module, I also get the same problem, but not a ModuleNotFoundError. Does anyone can give me some advice? Thanks a lot!
I think I found one possible reason of this error.
Recently I was configuring the caffe environment on one server, I downloaded the source code of opencv-2.4.13 and compiled manually, added /usr/local/opencv-2.4.13/build/lib to $PYTHONPATH, and caffe worked well. After that, when I entered one of my virtual environment using conda activate py35, which uses python3.5, tried import cv2 in the python prompt, got the error above.
I'm not sure but I think the cause of the error is opencv-2.4.13 compiles a python2 interface so it can't be imported by python3. Python imports packages by searching the directories listed in sys.path, where $PYTHONPATH is in the second place after the current working directory (This is a great article introduces the mechanism of python finding packages). So when we enter the py35 environment, python will first look for $PYTHONPATH and find the opencv installed on the root directory instead of finding the opencv in the virtual environment using conda install opencv-python.
So there are two solutions of this problem:
Use python2 instead.
Remove /usr/local/opencv-2.4.13/build/lib from $PYTHONPATH.
which all work for me.
Similar post, might help:
ImportError: dynamic module does not define init function (initfizzbuzz)
Could you provide info on how you installed the CV module?
I had the same problem, which was caused by the cv2.so file in /usr/local/lib/python2.7/site-packages/cv2.so. After I deleted the file and use command sudo pip3 install opencv-python, it worked for python3.
I have installed Anaconda for Windows. It's on my work PC, so I chose the option "Just for Me" as I don't have admin rights.
Anaconda is installed on the following directory:
c:\Users\huf069\AppData\Local\Continuum\Anaconda
The Windows installer has added this directory (+ the Anaconda\Scripts directory) to the System path.
I can launch Python but trying to run
x = randn(100,100)
gives me a Name Error: name 'randn' is not defined,
whereas, as I understood, this command should work when using Anaconda, as the numpy package is included.
it works fine if I do:
import numpy
numpy.random.randn(100,100)
Anyone understand what could be happening ?

The Anaconda distribution comes with the numpy package included, but still you'll need to import the package. If you want to use the randn() function without having to call the complete name, you can import it to your local namespace:
from numpy.random import randn
x = randn(100,100)
Otherwise, the call numpy.random.randn is your way to go.
