ImportError: DLL load failed while importing aggregations: The specified module could not be found

I am new to Python and currently having trouble when importing some libraries.

I am using Python 3.8.

I have installed Pandas in the CMD using "pip install pandas"

If i go to Python folder i see that Pandas is installed:

C:\Users\VALENTINA\AppData\Local\Programs\Python\Python38-32\Lib\site-packages

But then i get this error message when trying to import Pandas in my script:

Traceback (most recent call last):

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

I have this error message when running my script in Visual Code and also in IDLE.

I appreciate if someone can help me

Thnks


I was facing the same problem. I am using python 3.7.5. By default pip install pandas command install version 1.0.3. So i revert to version 1.0.1.

pip uninstall pandas
pip install pandas==1.0.1

Now it is working without error. You may try it.


You may also try to install a fresher version of Microsoft Visual C++ Redistributable.

E.g. (2015-2019)

I had the same problem, and installing the aforementioned resolved it.

There are two error messages I have received in importing pandas, the one in the OP and the other one being

AttributeError: module 'pandas' has no attribute 'plotting'

I was able to mitigate the issues by reinstalling the package/library

pip uninstall pandas
pip install pandas==1.0.1

as another user pointed out before me. I am using Python 3.8.2 in conjunction with pandas 1.0.1 without hiccup now.
