when executing “import pyodbc” in python 3.6 (anaconda3) Jupyter Notebook throws error: ImportError: DLL load failed

Question

What I want to accomplish:

• execute import pyodbc statement within Jupyter Notebook and thus use pyodbc to import data from sql databases such as SQL Server, Exasol, etc.

What is the environment:

• Anaconda3 (py36_0) installed on Windows 10 - 64 bit Version
• pyodbc installed via conda ( conda install pyodbc ) -> this worked as conda list shows that pyodbc 4.0.16 py36_0 is installed
• jupyter notebook works, for example import pandas works fine

What happens:

• after issuing the command import pyodbc within the jupyter notebook, the following error message appears:

  ImportError Traceback (most recent call last) in () ----> 1 import pyodbc ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.

Thanks in advance for any helpful answer!

Answer 1

I had the same problem. I don't think Anaconda is compatible with the latest pyodbc version. (see their website: https://docs.continuum.io/anaconda/pkg-docs which lists version 3.0.10 support for python 3.6)

I was able to solve this by downgrading my package using this command:

conda install -c anaconda pyodbc=3.0.10

This worked for me in my tests. Hope this helps. Please let me know if it does!

Answer 2

After translating the German error message, it appears you haven't installed pyodbc with Anaconda:

conda install -c anaconda pyodbc=3.0.10

That should solve your immediate problem, however, there may be some other tweaks to do to get pyodbc to run on Windows.

Answer 3

Updating pyodbc from 4.0.16-py36_0 to 4.0.17-py36_0 resolved the issue for me.

I ran the following conda command from the command line.

conda update pyodbc

Answer 4

I had the same problem

Go to https://anaconda.org/anaconda/pyodbc/files

And download https://anaconda.org/anaconda/pyodbc/3.0.10/download/win-64/pyodbc-3.0.10-py36_1.tar.bz2

In this adress \\Anaconda3\\Lib\\site-packages you look for the pyodbc.pyd and the .eggs-info file, you replace those files for the same file of the 3.0.10 version that is in the pyodbc-3.0.10-py36_1.tar.bz2.

That worked for me. Hope it also work for you
