psycopg2 - ImportError: DLL load failed while importing _psycopg: The operating system cannot run %1

I installed psycopg2 using conda on Windows 10.

https://anaconda.org/anaconda/psycopg2

I did it in a clean new conda environment (named wr).

I then tried to run this sample app but I am getting this error (see below). I have no idea what I might be doing wrong because it was all straightforward and I did it in a clean way.

Any ideas how to solve this?

import psycopg2
try:
    connection = psycopg2.connect(user = "***",
                                  password = "***",
                                  host = "***",
                                  port = "5432",
                                  database = "***")


    cursor = connection.cursor()
    # Print PostgreSQL Connection properties
    print ( connection.get_dsn_parameters(),"\n")

    # Print PostgreSQL version
    cursor.execute("SELECT version();")
    record = cursor.fetchone()
    print("You are connected to - ", record,"\n")

except (Exception, psycopg2.Error) as error :
    print ("Error while connecting to PostgreSQL", error)
finally:
    #closing database connection.
        if(connection):
            cursor.close()
            connection.close()
            print("PostgreSQL connection is closed")

Error in VS code:

EDIT: Seems they had a bug open for this 2 years ago and they just closed it, ignoring it completely.

You can use psycopg2-binary library instead of psycopg2. After installation the usage is the same.

psycopg2 requires some dll file to be installed on your operating system. You can either install it manually or you can install psycopg2-binary instead which packs both the library and dll files together.

The documentation resides in psycopg2 library docs: https://psycopg.org/docs/install.html
