I am trying to get boost 1.69 working with visual studio 2107. My goal is to use Numpy in C++
When I include #include boost/python/numpy.hpp
The error I am getting is:
Searching C:\boost_1_69_0\stage\lib\boost_python37-vc141-mt-gd-x32-1_69.lib:
1>LINK : fatal error LNK1104: cannot open file 'boost_numpy37-vc141-mt-gd-x32-1_69.lib'
I am pretty sure that I have this file in this directory.
My architucture in the project is x86, 32-bit addrressing
I built boost as follows:
.\bbotstarp.bat
.\b2 -j8 --toolset=msvc-14.1 --build-type=complete link=static runtime-link=static architecture=x86 address-model=32 stage --with-python
I added the include and link folders to the project.
I do not use precompiled headers
Is there anything that I am missing?
Thanks
I had the same problem. It seems like Boost python is not supported by python 3.7 vert well.
Using python 3.6 will solve this problem.
I have been looking at this issue for months and finally figure out the root cause and solutions. The root cause that boost numpy is not built is because numpy is unable to be imported when ./b2 checks for numpy. As a clue from this post Using boost numpy with visual studio 2019 and python 3.8, you can append --debug-configuration to see the debugging information of boost python building process like this in my PC
notice: [python-cfg] Checking for NumPy...
notice: [python-cfg] running command 'C:/Anaconda3_Install_Root/envs/my_envs/python -c "import sys; sys.stderr = sys.stdout; import numpy; print(numpy.get_include())"'
And, the error comes from ImportError for some reason:
ImportError: DLL load failed while importing _multiarray_umath: The specified module could not be found.
After looking at this post numpy is already installed with Anaconda but I get an ImportError (DLL load failed: The specified module could not be found), I found this import process has to be under python environment such as under conda environment or PyCharm terminal (They both work in my PC) with all the required PATH to be imported. Now I can generate numpy static library with Python 3.8, VS 2019, boost v1.74, Windows 10. The command I use to build boost python is .\b2 --with-python python-debugging=off threading=multi variant=release li
nk=static address-model=64 stage --debug-configuration. Hopefully, that will work in yours.

I'm on a Mac X1, Monterey.
I've installed prophet and run into this issue when trying to fit a model.
RuntimeError: Error during optimization: console log output:

Reason: tried: '/private/var/folders/cd/dfrqgp4s4ll55cwb7rtgccbw0000gq/T/pip-install-rjpuj450/prophet_d7e4cce10e414c89a572fe3605ae9269/build/lib.macosx-11.1-arm64-cpython-39/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/libtbb.dylib' (no such file), '/private/var/folders/cd/dfrqgp4s4ll55cwb7rtgccbw0000gq/T/pip-install-rjpuj450/prophet_d7e4cce10e414c89a572fe3605ae9269/build/lib.macosx-11.1-arm64-cpython-39/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/libtbb.dylib' (no such file), '/usr/local/lib/libtbb.dylib' (no such file), '/usr/lib/libtbb.dylib' (no such file)
I know this has to do with the wrong paths being searched. I can find the dylib in
/Users/{user}/opt/anaconda3/lib/python3.9/site-packages/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/
But, it seems prophet doesn't know to look there. I'm curious how I can update/fix either the rpath variable or find another solution?
I tried to create a symbolic link with sudo ln -s, but don't have permissions on the laptop.
TIA!
I got it to work on Apple Silicon (M1 Max in my case) by installing older versions of both pystan and prophet:
pip install pystan==2.19.1.1
pip install prophet==1.0
The other important piece of the puzzle is that you should use Python 3.8 to get it working.
Installing older versions of the libraries and using Python 3.8 are both talked about in issue #2002 on Github, but there's not really an explanation of the libtbb.dylib error message.
I'm trying to build a visual dashboard in VS Code using dash. But I can't get past this error I'm getting:

I'm using python 3.6.13 but I've tried this with python 3.9 and 3.8. I also tried installing\uninstalling numpy and pandas. I'm using Anaconda for my package management. Any help would be really appreciated!

Assuming that Bas may be right, and you're missing the Microsoft C++ compiler. Try installing Microsoft's "C/C++ Extension Pack": https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools-extension-pack . You can find it in VSCode by clicking the extensions icon at the left side and searching "cpptools".
Since I'm using conda, I updated conda and then updated all of my packages and that worked.
conda update conda
conda update --all
Note: I'm on Python 3.9 on a Windows machine.
Probably unnecessary, but I also added the interpreter path to my launch.json file:
"python": "C:\\Users\\<username>\\Anaconda3\\python.exe"
After installing Anaconda on a Virtual Machine I run a script which is working on my local machine but not on my Virtual Machine.
I'm getting the error Message:

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.8 from "C:\ProgramData\Anaconda3\python.exe"
* The NumPy version is: "1.18.5"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

The VM has no Internet. Is there any way to install all the required libs and frameworks?
You can package your script and used libraries using something like Pyinstaller. When you use an virtualenv keep in mind that all the packages that you use during pyinstaller execution are stored and may lead to an huge .exe

Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "C:\USERS\YADAVP\ANACONDA3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

What is the resolution to sort this kind of error in Power BI?
Forget Anaconda and use WinPython.
I tried Anaconda for days with all the workarounds available in StackOverflow and other forums, and they took me nowhere.
Then I tried WinPython, and it worked immediately. Of course, you will need to change the PowerBI options accordingly.
To install WinPython: https://github.com/winpython/winpython
To change the detected Python home directory: https://learn.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#enable-python-scripting
If you consider my answer, you won't need to downgrade Python, PBI, or anything else.
I had the same error. Unfortunately, PowerBI wont work with Jupyter Notebook Python.
So you have to install a "normal" Python: https://www.python.org/downloads/
And configure the Python you want to use in PowerBI and install your needed Python libraries via pip
Edit: Please use Python 3.8 because 3.9 doesnt support NumPy for now
I’m having trouble compiling some FortranIV code using f2py and the g77 compiler. I need to do this to call some very old code written in Fortran to an already existing Python module. I have gcc installed through MinGW but I’m not sure if that makes any difference. I am also running Python 2.7 with Numpy 1.7 and SciPy 0.12. My OS is Windows7 x64 but I have made sure that all my installs are 32bit versions. I am new to Python, Fortran and this forum so please bear with me.
The error I am getting when I compile the code with f2py is as follows:
C:\Python27\lib\site-packages\numpy\core\include\numpy\npy_common.h:291: limits.h: No such file or directory
error: Command "gcc -mno-cygwin -mdll -O2 -w -Wstrict-prototypes - DNPY_MINGW_USE_CUSTOM_MSVCR -D__MSVCRT_VERSION__=0x0900 - Ic:\users\ncd69~1.boh\appdata\local\temp\tmpxbl4sc\src.win32-2.7 -IC:\Python27\lib\site- packages\numpy\core\include -IC:\Python27\include -IC:\Python27\PC - c:\users\ncd69~1.boh\appdata\local\temp\tmpxbl4sc\src.win32-2.7\hellomodule.c -o c:\users\ncd69~1.boh\appdata\local\temp\tmpxbl4sc\Release\users\ncd69~1.boh\appdata\local\temp\tmpxbl4sc\src.win32-2.7\hellomodule.o" failed with exit status 1
In order to isolate the problem I have used a test code that is compatible with the gfortran compiler. I make a call to the required compilers using ‘-c –compiler. The test is on the same lines as your basic ‘Hello World’. The error thrown up is identical for the real and test code. I looked up the erroneous file ‘npy_common.h’ and found that line 291 calls to include a header: limits.h.
Since the error occurs in the Numpy libraries I am assuming that the error is with Numpy? I can’t seem to figure out why this error would occur.
