I am trying to run some C++ code with embedded Python. Code was working completely fine a couple of weeks ago. The code still compiles, but I am now getting the error

Since then the only change I have made is to install the macOS Supplemental Update and to upgrade Python from 2.7.13_1 to 2.7.14_2 (using Homebrew). I have changed the relevant linker flags in the makefile, i.e. those that appear when I type python-config --ldflags. I have also made sure that the Python I am using is definitely the Homebrew one by inserting export PATH="/usr/local/opt/python/libexec/bin:$PATH" into my .bash_profile as directed by Homebrew.
I am not sure whether this error is because of the Python update, the recent macOS Supplemental Update, or something else. Any idea what the problem could be?
Thanks
I had the same problem;
In python 2.7 the NumPy 1.8.0 was available,
Then I installed NumPy (again) using brew, and it wasn't available in my python (2.7) anymore. (Got the same error you got here)
So I did "brew unlink python && brew link python" to use python 3 (instead of 2) which NumPy 1.14 is available in it.
I guess the python 2.7 was not compatible with this recent version of NumPy.

ImportError: DLL load failed: The file cannot be accessed by the system.
Got this error while trying to run some already used python scripts on pycharm. Has anybody had this error before and has he solved it? It started after I installed a package in python but never used it. The problem is located when I try to import train_test_split on scikit-learn and tensorflow, the sklearn package and seaborn. The other parts of the code seem unaffected.
I have already reinstalled anaconda and python as well as changing the python files. Any help would be greatly appreciated.
After reinstalling the python as well as updating all the packages (conda update --all) and changing the PATH file, it seems that the issue is solved in all of my IDE's except PyCharm. It seems that all that remains is an interpreter issue. I will post updates if something else comes into my attention.
I am trying to use tensorflow for research in my macbook. I use pip3 to install tensorflow in the system (not in virtual environment).
At first, I just want to verify tensorflow can be correctly imported via python3 in terminal. However, sometimes, I got the following problem when importing.
>>>import tensorflow as tf

This error could only be solved if I ran the following code firstly before python3 execution
unset PYTHONPATH
If I didn't unset PYTHONPATH, I also found errors when checking the version of pip3 using
pip3 --version
The errors are shown as follows.
>> pip3 --version

raise ImportError('This package should not be accessible on Python 3. '
ImportError: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.
I thought it was so inconvenient to unset PYTHONPATH every time, so is there any solutions for this problem? I also want to import tensorflow in other text editor, such as Sublime and Pycharm, so I was really not sure what to do next.
I tried the same scenario. It is working fine for me. In the first error it seems your python installation is messed up. If you are using python3 in terminal, it should not refer to 2.7 libraries.
Also I dont think you require unset PYTHONPATH everytime. First thing is you dont need to setup PYTHONPATH. It seems the installation got issue.
You using homebrew in mac to install packages. If not I will say use homebrew and it will work as charm. As it adds dependency properly.
Thanks,
Ashish
I would like to call a python function from C++ and get the return value. I've been able to do that with an easy multiply python function using this website's example code in section 5.3. To compile my program, I would run g++ test.cpp -I/usr/include/python2.7 -lpython2.7. However, the python function I want to run imports numpy. When I try to run my program that is similar to the one on the code example mentioned above, I get an "ImportError: cannot import name _remove_dead_weakref". The full error is here:

Some information: Python version is Python 2.7.14 :: Anaconda, Inc. (Is there a difference between python 2.7.14 and my version which has anaconda, inc. at the end?) The python program also runs just fine by itself. Any help would be appreciated. Thanks!
Edit: The path was being all weird with some parts going to my local python and numpy going to miniconda's python. Uninstalling miniconda as it wasn't needed for me fixed it.
This is happening because your environment is mixing two different Python installations. You can see it jump between them here:
File "/home/osboxes/.local/lib/python2.7/site-packages/numpy/testing/__init__.py"
File "/home/osboxes/miniconda2/lib/python2.7/unittest/__init__.py"
So you start out in /home/osboxes/.local/lib/python2.7/site-packages which is the Python installed by some system package manager (or perhaps even explicitly installed from source). But then it jumps to /home/osboxes/miniconda2/lib/python2.7 which is from Conda.
Since it appears you are intending to use Python from Conda, you need to install NumPy using Conda (so it is loaded from miniconda2 and not .local, and build your code using something like -I/home/osboxes/miniconda2/include/python2.7 instead of -I/usr/include/python2.7.
I'm trying to use the Reticulate package to use Python through R. I successfully connected Reticulate to Python 3.6 with Sys.setenv(RETICULATE_PYTHON = "/usr/local/bin/python3"). Then after noticing that my Python 3.6 didn't have Numpy, I used entered pip3 install numpy into the command line and installed it. Now, I am having the following problem with Reticulate when I call py_config():
py_config()

Can anyone tell me what's going on and how I can fix it?
I have default and anaconda python, theano is installed in conda moreover it was also part of anaconda for keras. I am trying to exec a python file from another folder as python ---- and everything is ok except from theano.tensor.fft import ifft where it says no module named theano.tensor.fft I have added PYTHONPATH I have separately added theano in site-package but i can not figure out why it can not import module, please note that I can import theano.tensor I am trying to run MarcBS/keras caffe2keras.py
this is what I got when trying to install theano
