I am attempting to use cuPy to speed up some background numpy operations in my python code but when attempting to import cupy I am told that the DLL load failed and the module could not be found, cupy_backends.cuda.libs import nvrtc. (Specific errors at end of post)
I've attempted almost everything the error message suggests. I check my version of cupy and cuda which are cupy-cuda111==8.4.0, I have Cuda 11.2 installed as well. I am running Windows 10 and Python 3.7.6 on Spyder 3. I have tried uninstalling cupy via pip uninstall in hopes of reinstalling correctly but it just hangs and never uninstalls the package.
It appears I have the file its looking for when I go search manually via my file explorer. (Imaged Below)
I am fairly inexperienced when it comes to handling things like this so any help would be greatly appreciated. The entire error message and trace is copied below:

Also, confirm that only one CuPy package is installed:
$ pip freeze
If you are building CuPy from source, please check your environment, uninstall CuPy and reinstall it with:
$ pip install cupy --no-cache-dir -vvvv
Check the Installation Guide for details:

getting up to speed on Anaconda, I keep receiving an error message when I try to import 'numpy' into Python.
Here is what I have done so far:
Downloaded anaconda from anaconda.com (64-Bit Graphical
Installer (466 MB) with Python 3.7 for Windows);
Installed anaconda (under C:\Users\'Username'\Anaconda3 | Option 'Register Anaconda3 as my default Python 3.7')
Now I'm trying to import numpy into Python using idle.exe, which produces following error message:
Warning: os.path.expanduser("~") points to
h:\,
but the path does not exist.
Futhermore, after executing "'import 'numpy;" in IDLE I get the following error message.
Unfortunately none of the advice was helpful. Numpy seems to be properly installed.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
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\'Username'\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.
Original error was: DLL load failed: The specified module could not be found.
Many thanks in advance for any help and suggestions.
I am using python 3.7
Recently I started getting this error while importing sklearn module.
I get the same error in Jupyter Notebook, Python IDLE, Pycharm virtual environment
>>> import sklearn
Traceback (most recent call last):

I have tried reinstalling too.
After that I copied contents of sklearn of venv of another project which had no issues. This thing worked for couple of times. But now it's not working again
Note: pandas, numpy, scipy etc are installed and working absolutely fine. Sklearn was also working fine few days back
This is an issue in the packaging in scikit-learn 0.22.0 which will be solved in 0.22.1 (released next week). The issue is tracked at: github.com/scikit-learn/scikit-learn/issues/15899. There are 2 possible workarounds:
Install scikit-learn from conda-forge (conda include the missing dll) by default: conda install conda-forge::scikit-learn
Install VC++ which will have the openmp library (https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)
I am just a beginner to a tensorflow and trying to install TensorFlow with CPU support only.
Initially, I downloaded and installed Python 3.5.2 version from https://www.python.org/downloads/release/python-352/
After successful installation, I ran the command pip3 install --upgrade tensorflow which installed tensorflow-1.8.0.
To test installation i just ran following commands:
> python
> import tensorflow as tf
But this gave me an error:
ImportError: Could not find 'msvcp140.dll'. TensorFlow requires that
this DLL be installed in a directory that is named in your %PATH%
environment variable. You may install this DLL by downloading Visual
C++ 2015 Redistributable Update 3 from this URL:
https://www.microsoft.com/en-us/download/details.aspx?id=53587
I searched for this issue and found link to an issue https://github.com/tensorflow/tensorflow/issues/17393.
According to above i tried running command
pip install tensorflow==1.5
But, this didn't solved my problem.
I even tried downloading msvcp140.dll and manually coping it under C:\Windows\SysWOW64 folder and reinstalling python and tensorflow.
How do I fix this problem.
Thanks in advance.
I copied msvcp140.dll to path C:\Users\PCName\AppData\Local\Programs\Python\Python35
and it worked for me.
I also switched back to tensorflow 1.8 from 1.5.
download msvcp140.dll or click https://www.dll-files.com/msvcp140.dll.html
find your python path
path will find easy from your error
error will show like this

if u cant find the AppData folder
click folder view option and enable hidden files
paste the file "msvcp140.dll" into

This looks like some of the dependencies are missing for the package numpy. The DLL load failed error points towards either incorrectly installed and/or missing files for package numpy. You should just try installing numpy again through Anaconda CLI using the following command:
conda install numpy
This works most of the times, if your python environments are sorted correctly. Do make sure that the python installation you're using for Anaconda, is the same one as your coding environment. Conflicting versions can sometimes lead to corrupted packages.
You could also try the following command to update the Anaconda Environment just to make sure that the installations are up to date, and not conflicting with older versions..
conda update -y -all
I'm trying to call a function from the cluster module, like so:
import sklearn
db = sklearn.cluster.DBSCAN()
and I get the following error:
AttributeError: 'module' object has no attribute 'cluster'
Tab-completing in IPython, I seem to have access to the base, clone, externals, re, setup_module, sys, and warning modules. Nothing else, though others (including cluster) are in the sklearn directory.
Following pbu's advice below and using
from sklearn import cluster
I get:

I'm using Python 3.4 on Windows, scikit-learn 0.16.1.
You probably don't use Numpy+MKL, but only Numpy.
I had the same problem and reinstalling Numpy with MKL
pip install --upgrade --force-reinstall "numpy‑1.16.3+mkl‑cp37‑cp37m‑win32.whl"
fixed it.
Note: update the file to the latest version, possibly 64bit - see the list of available Windows binaries
Problem was with scipy/numpy install. I'd been using the (normally excellent!) unofficial installers from http://www.lfd.uci.edu/~gohlke/pythonlibs/. Uninstall/re-install from there made no difference, but installing with the official installers (linked from http://www.scipy.org/install.html) did the trick.
I am using anaconda got the same error as the OP, when loading Orange, or PlotNine.
I can't recall when this start to happen.
Tracing the dependency of Anaconda3\Lib\site-packages\scipy\special\_ufuncs.cp36-win32.pyd, libifcoremd.dll and libmmd.dll are missing in DependencyWalk. Searching them in anaconda root directry, they are located in both ICC_RT and one version of MKL package.
Adding Anaconda3\pkgs\mkl-2017.0.3-0\Library\bin to PATH, seems to fix SciPy and NumPy related DLL load failure, the above package starts to work again.
I still don't know how to fix this properly. Apparently the downside is that the MKL package could be updated and versions may change so does the path. In this aspect Its equally inconvenient as adding a non-managed package.
Reinstalling ICC_RT fixed the issue for me, libmmd.dll and the related dlls are automatically copied into anaconda3/library/bin afterwards, which is automatically added into PATH by activate command. All previous numpy/scipy related cant load DLL errors are gone now.
From the error log, it shows that scipy module is the most recent module fails to import

ImportError: DLL load failed: The specified module could not be found.
I have the same error that show the same log, the problem'd gone when I uninstall/install scipy:
pip uninstall scipy
pip install scipy
Place this line on top of the python file
from sklearn import cluster
That should do it :))
For me what fixed it were these commands:
pip uninstall sklearn
pip uninstall scikit-learn
pip uninstall scipy
pip install scipy
pip install scikit-learnhere
I had the same issue and solved it by installing/updating the mkl package:
conda install mkl
or
pip install mkl
Just for full information, this also downgraded the following packages:
The following packages will be UPDATED:
mkl: 2017.0.4-h6d528fc_0 defaults --> 2018.0.3-1 defaults
The following packages will be DOWNGRADED:
numpy: 1.11.3-py34_0 defaults --> 1.10.1-py34_0 defaults
pandas: 0.19.2-np111py34_1 defaults --> 0.18.1-np110py34_0 defaults
scikit-learn: 0.18.1-np111py34_1 defaults --> 0.17-np110py34_1 defaults
scipy: 0.19.1-np111py34_0 defaults --> 0.16.0-np110py34_0 defaults
I struggled trying to figure this one out; tried to download and install the (unofficial) Numpy+MKL library from the website (risky/tedious?).
Ultimately found success by:
Login to command prompt using admin rights; how to here: https://superuser.com/questions/968214/open-cmd-as-admin-with-windowsr-shortcut
Uninstall existing/tangled version of Scipy & Numpy
pip uninstall scipy
pip uninstall numpy
Fresh install Scipy & Numpy
pip install scipy
pip install numpy
Run Jupyter notebook; it worked for me.
The message ImportError: DLL load failed: The specified module could not be found
informs that there is failure to identify and source the required DLL(s) to use the scikit-learn library; a fresh install of scipy/numpy probably enables a better routing of DLL connections called from Jupyter notebook code(s).
download microsoft visual c++ distribution
link : https://www.microsoft.com/en-in/download/details.aspx?id=53840
vc_redist.x64.exe
install and run this .exe file in your computer.. the DLL import module error will not appear after this
now it will work fine enjoy :)
