Installed pandas not able to import with:

ImportError: DLL load failed: The specified module could not be found.

As far as we know, this happens if you install with pip on Windows 32bit machines (if you have another case, please comment below with specifying your OS, Python version, how you installed pandas, ..).

Workaround for now is to keep your version at pandas 0.22.0. (or to install using conda, or to install VS tools for C++, see #21106 (comment))

We will fix this problem for 0.23.1.

How did you install python? You seem to be on 32 bit windows which is less tested, but I just tried with a clean conda environment and it worked fine

set CONDA_FORCE_32BIT=1
conda create -n py36_32 python=3.6 numpy -y
activate py36_32
pip install pandas
python -c "import pandas"

I can confirm this issue is due to 0.23
Uninstall then reinstall 0.22

pip uninstall pandas
pip install pandas==0.22

@asangansi can you please give the additional information as mentioned here #21106 (comment). That would be helpful.

As far as I can tell most of my students have libraries similar to this(copy from pyCharm settings):
et-xmlfile 1.0.1
jdcal 1.4 1.4
numpy 1.14.3 1.14.3
openpyxl 2.5.3 2.5.3

pip 9.0.1 10.0.1
python-dateutil 2.7.3 2.7.3
pytz 2018.4 2018.4
setuptools 28.8.0 39.2.0
six 1.11.0 1.11.0
xlrd 1.1.0 1.1.0

Python 3.6
Project in PyCharm 2018.1.1

Not a whole lot to go on here, but @cgohlke do you have any guesses?

FWIW, _window.pyx is the first C++ pyx file in

pandas/setup.py

Line 334 in 1abfd1b

_cpp_pyxfiles = ['pandas/_libs/window.pyx',

Here's another failed attempt to repro, using a python.org binary.

# download, unzip, cd to root of  https://www.python.org/ftp/python/3.6.2/python-3.6.2-embed-win32.zip
rm python36._pth
curl https://bootstrap.pypa.io/get-pip.py > get-pip.py
python get-pip.py
python -m pip install pandas
python
>>> import pandas

c++ is probably the issue, guessing missing the runtime DLL, though I'm not sure the best fix. From what I recall c++ wasn't particularly necessary for that change so could revert back to c for 0.23.1

Could someone one this issue try install the VS 2015 Redistributable and see if that fixes it for you?

cgohlke commented May 23, 2018

The missing DLL is most probably MSVCP140.DLL, the MSVC C++ runtime library.

It is part of the Microsoft Visual C++ Redistributable for Visual Studio 2015/2017.

Some projects, e.g. matplotlib, include this DLL in the binary wheels.

we have used c++ for quite some time

@jorisvandenbossche
Copy link

But we were not using libcpp in cython code before. @jreback might that be a difference with previous c++ code of msgpack?

@chris-b1

Contributor

That's right, msgpack only depends on libc, where the window extension is utilizing the c++ std library.

@chris-b1 can you see what mpl is doing? maybe need a directive in setup.py? or the wheeel building step

@jorisvandenbossche

@cgohlke is this something you want to do? (including the binaries? similar as matplotlib) (since we are using your wheels to upload to pypi)

Any updates on this? (somebody who can look at fixing the wheel building?)

Otherwise we can also revert the PR (it was only a performance improvement) for 0.23.1, but keep it in master so have more time to fix the wheel building for 0.24.0.

Could someone reporting on this issue (@manish59, @sionking, @asangansi, @abador, @mezitax ) please confirm that installing the redistributable fixes this for 0.23? Every windows machine I have access to already has it installed.

I'll look at what matplotlib does later today.

Yes. By uninstalling 0.23 and reinstalling 0.22 of pandas the problem is resolved. Thanks

I ran into the same issue on my Windows 10 x64 VM with Python 3.6.5 (64-bit). The exception was raised when version 0.23.0 was installed and was resolved when I downgraded to 0.22. It was also resolved by installing the MSVC++ redistributable.
