I am tring to call VectorBT using C#, a python package for backtesting.
Meeting the below bug:

Any suggestion?
Does Anaconda3 contain the VectorBt package?
Environment: Visual Studio 2022 + Anaconda3
I found the reason, it's because that anaconda3 does not contain the package "vectorBT". But when I install using
"conda install vectorbt", I got the below notice “package not found error, the following packages are not available from current channels”

follow up question: how to install vectorbt to anaconda3?

I think this is a Python issue. but I'm running Python3:
python -V shows
Python 3.9.0
I have installed it with homebrew.
What can be the problem?
This is a known issue across Mac, Windows and Linux: https://issuetracker.google.com/170125513.
I'd suggest to use the recommended Python versions mentioned here (3.5 to 3.8).
Also this does not affect only to Cloud SDK but others as well (for example as mentioned here).
Thanks for your answer. Indeed, it works with the version 3.8.6 of python.
I will add some infos if it can help somebody. In order to manage python version, I have used pyenv and installed the version of python I needed.
pyenv install 3.8.6
pyenv global 3.8.6
If you want a quick fix you can add this to your bash profile and restart your terminal:
export CLOUDSDK_PYTHON=python3.8
Worked for me
I am trying to use Keras_ocr for a project, but I can't get it to import to my script. I am using tensorflow backend (non-gpu).
Here is the error code I am receiving:

I installed keras_ocr via pip.
This is a known issue where Keras_ocr finds the wrong DLL or can't find it at all. It can be solved simply by updating Keras_ocr or uninstalling and reinstalling keras_ocr.
Try installing Python=3.6 and the latest Tensorflow version, after that install keras_ocr.
That should work.

As referred in this link that looks similar. You probably dont have c++ windows compiler. You will need to install Visual C++ Redistributable and then reinstalling anaconda might solve the issue.
On a side note anaconda generally takes care of the installing of the c++ compiler. Did you create virtualenv and pip install. I will suggest you install using conda install.
conda install scipy
I recently installed python on my Ubuntu 14.04. I downloaded tensorflow by pip.
When I tried to import tensorflow it said ImportError:No module named tensorflow.
Then I edited PYTHONPATH by adding /usr/local/lib/python2.7/dist-packages. Now when I try to import, it says

I found here that 2 versions of python causes the conflict, but that didn't help. Any assistance will be appreciated. Thank you
Best way to install packages if you have more than one python installed is:
path_to_your_python_executable -m pip install package_name
This way, you can make sure that you have installed package for proper python.
And don't forget about sudo ;)
I'm new to Linux and generally installing packages via command line syntax.
I've tried installing numba (to use jit) into Python and this is the error I receive.I did this originally with GitHub source, and again with Anaconda. Numba appear to be installed correctly in the command line, however when I try to import into Spyder I get the below error
