Python SDK

I upgraded my sdk version from 2.5 to 3.2 using below command in Anaconda Prompt

“python -m pip install couchbase==3.2 --upgrade”

installation is successful but while doing “import couchbase” I’m getting the below error

ImportError: DLL load failed: %1 is not a valid Win32 application.

I use windows 10

anaconda version 4.5.4

output of python -c “import sys;print(sys.version)” is as below
system version 3.6.5

libcouchbase was not installed previously

Anyone please help me resolve this issue.

Hi @Kratos - The information provided seems incomplete. Can you please provide the output of the command following command? I have pasted below that what I would expect to see.

Command:

python -c "import sys;print(sys.version);print(sys.path)"

Output:

(C:\ProgramData\Anaconda3) C:\Users\Administrator>python -c "import sys;print(sys.version);print(sys.path)"

How did you previously install the 2.5.x Python SDK? libcouchbase was not built in place and I believe there are only wheels for Python >= 3.7.
Also, can you show the entire output of the error? I would expect there should be a stack trace as well.
