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 now trying to run qiskit visualization functions(e.g. .draw() methods) in vscode.
I use latest version of Python, 3.11.1, and followed Getting Started Qiskit in here.
Also I installed qiskit extension in vscode.
However, when I run a qiskit code, the visualization functions don't work, even though code is compiled successfully.
I checked visualizing modules(mathplotlib, etc.) were installed.
I tried to re-install Python and vscode, including downgrading Python to 3.8. And it didn't work.
Additionally, qiskit-chemistry and qiskit-aqua installation warnings are pop-upped, but installation doesn't work.
I really don't know it is related on this problem, but I think maybe it's not since qiskit-aqua is deprecated.
The following screenshot is result of the qiskit test code.
result of running
draw() and plot_histogram() doesn't work as you can see.
How can I fix this problem?
These functions are meant to be used in Python Notebooks - they won't show up in normal .py files. Try using VSCode's Jupyter Notebook (.ipynb files) feature instead.
I am quite new to python and only did smaller projects so far. For a new project I would like to use FEniCS for solving PDEs. I am working with Windows 10 and already successfully installed Ubuntu (I still do not entirely understand what Ubunutu is needed for). To test solving a PDE I executed a tutorial file "ft01_poisson.py" from the website of the FEniCS project (https://fenicsproject.org/tutorial/) in the Ubuntu command window and it worked.
Afterwards, I also wanted to execute the file in spyder since I will use Spyder for my own project to solve PDEs. I did pip install fenics and when I repeat the command it says Requirement already satisfied: fenics c:\users\airwaves12\anaconda3\envs\spyder-4.1.5\lib\site-packages (2019.1.0).
But when I execute the script in spyder I always get the error ModuleNotFoundError: No module named 'fenics'. In the above-mentioned path there are only folders called fenics_dijitso-2019.1.0.dist-info, fenics_ffc-2019.1.0.post0.dist-info, fenics_fiat-2019.1.0.dist-info, fenics_ufl-2019.1.0.dist-info and fenics-2019.1.0.dist-info.
I know that the "fenics package" consists of different subpackages as "ffc", "FIAT", "ufl" or "dijitso". Those also excist in the above-mentioned file. I tried to manually copy those subpackages saved in folder called "fenics" into the path C:\Users\Airwaves12\anaconda3\envs\spyder-4.1.5\Lib\site-packages but that obviously did not work cause python did not find for example the function UnitSquareMesh().
I spend almost two days reading everything concerning this topic and tried out a lot of things but the most useful advice was from No module named 'dolfin' using Spyder which did not work for me and was originally just for anaconda. How to use FEniCS in Jupyter Notebook or Spyder? did not get an answer for spyder so far.
Does anyone know how to properly use FEniCS with spyder? I would be grateful for any advice.
I was working on using the Simple Transformers python library from here when I got a Windows error with following error when running the example code on the import statement from simpletransformers.classification import ClassificationModel:
"The procedure entry point cusparseGetErrorString could not be located in the dynamic link library cusparse64_10.dll"
I've tried reinstalling the relevant within the Conda environment as described on the GitHub, reinstalling CUDA itself and running a registry cleaner but I haven't been able to help this issue and I've run out of ideas to approach this, so I would appreciate any help.
CUDA has been working fine for me outside of Conda environments previously.
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.

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 use conda update --all to update my packages. Recently, I encountered an error with Anaconda build, posted at Error while trying to update and use scipy module in Anaconda. It seems now the issue has been fixed. Is there any way, I can test all modules one by one by importing them and deleting them ? I am requesting this because I have noticed that if import doesn't work, I spend a lot of time figuring out the dependency and then the package that is causing this. For instance, a few minutes ago I found that PyCharm 2018.2.4 breaks with the latest version of matplotlib (3.0.0). Hence, it might be helpful to run some type of test script after running conda update --all to ensure that all packages are indeed working--i.e. importable.
I did some research on this topic and found three sources.
First, Anaconda offers run_test.py (Source: https://conda.io/docs/user-guide/tasks/build-packages/recipe.html). However, being new to the world of Python, I am unsure how to go about running a script in Anaconda terminal.
Second, I found: https://conda.io/docs/user-guide/install/test-installation.html. However, this just tells me the version of the package. I am not interested in the version. I need to know whether all packages import properly.
Finally, I found out that there is a method to run test script for all packages at https://anaconda-installer.readthedocs.io/en/latest/testing.html. However, I am unsure how I can run make in Anaconda terminal. I used to use make long time ago when I worked on gcc on Unix environment. Being new to Python, I am unsure how to go about handling this.
I'd appreciate any thoughts or any test script that could help us verify two things:
a) whether all packages have been installed
b) packages are indeed importable; If the package import fails, the script should terminate with handsome error message highlighting the source (package) where import failed.
