Python script ADO.net error: The file is too long.

[KimDongmin]

I am visualizing using python script with power bi desktop. However, I downloaded a new desktop version to update the Power bi desktop, After that, refreshing the Python script will cause an error.

message :

ADO.NET: A problem occurred while processing your Python script.
Here are the technical details:
The file is too long.
This operation is currently limited to supporting files less than 2 gigabytes in size.

The code worked fine until I downloaded a new desktop, but now i get the above error

Do you know how to fix it?

@KimDongmin , just check have you installed 32-bit python on new machine

I have installed the 64 bit version of Python, I am facing the exact same issue. My file size is 3.7gb and I am using Python script to read the data from a s3 bucket.
