I would like to access FME Objects from my Python Code. But I don't understand how to import fmeobjects, which is the correct folder to copy in the Python folder ?
I just need to do a simple thing : i have an AutoCAD .dwg file as input in FME and i would like my Python script to go through the layers in the dwg file and to print the name of those layers. (something that FME does using Mapping File Generation to merge the schema features from the dataset).
Thanks,
Paul

This is the dynamic module file for the fmeobjects.
<FME Installation Folder Path>\\fmeobjects\\python27\\fmeobjects.pyd
Copy it into "<Python Home>\\Lib\\site-packages" folder.
OR, append a searching path in your Python script like this.
-----
import sys
sys.path.append('<FME Installation Folder Path>/fmeobjects/python27')
import fmeobjects
-----
But I'm not sure whether the module works with Python 3.x, since it is implemented with Python 2.7.x.

[A] Install Python 2.7 to your machine.
[B] Embed the script into an FME workspace (startup or PythonCreator/Caller script) and execute it with FME Workbench.
[C] Create a new FME workspace to do the same thing without scripting. The Schema (Any Format) reader can be used to get layer names.
Thank you !
Option [A] is not possible for me.
Option [B] : this could work. I write a code that goes through the layers in the dwg and writes the result in a Published Parameter that I can use after. What do you think ?
Option [C] : this could work too, but i don't see how the Schema Reader can be used to get layer names ?

[C] Just add a Schema (Any Format) reader to the workspace with setting the dwg file path to its Dataset parameter. The reader will create features having schema information for each layer in the specified dwg file. Each schema feature has an attribute called "fme_feature_type_name" that stores the layer name.
The Schema reader approach might be easier than other approaches.
+19In the Reader, i used the autocad_layer in the Format Attributes to get the names of the layers. Then I copied them into a new Attribute but i don't see how can I pass these values in my Python script and my GUI.
+19But I cannot decide what is the best way since I'm unclear what your requirement is.
What's the purpose to get the layer names?
I am using the Amazon s3 bucket modified listener to trigger a workspace and process data as soon as it enters our bucket. Some days ago we had to change the region settings and since then i am getting this error:
2021-07-12T10:32:29Z | An error occurred: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'us-east-2' (Service: Amazon S3; Status Code: 400; Error Code: AuthorizationHeaderMalformed; Request ID: ********; S3 Extended Request ID: *****)The FME server version is 2020.1.3.2, i don't have access to the config files of the server. Is it possible to set the region of the listener manually somehow or a trick to solve the problem? I tried same connection on another instance of the FME server and i had no problems there.
+19Alternatively, there is a way to prompt a message box just to inform layer names to the user. See this old QA.

However I'm experiencing some issues : when I choose my dwg file through my GUI, I'm not sure it correctly opens all the layers in FME (ie : when you have a Reader that is a dwg/dxf format, FME asks you which layers you want to upload ; it is this part that I'm having trouble with).

This is another discussion on how to collect feature type names and display them with a dialog, using the Schema reader and a PythonCaller.
select different feature type each time workspace runs (https://knowledge.safe.com/CommunityAnswers#!/feedtype=SINGLE_QUESTION_SEARCH_RESULT&id=906a0000000d27zAAA)

I am using C:\\Python27\\ArcGISx6410.3 for running my scripts. No I want to use fmeobjects from my folder C:\\Program Files (x86)\\FME\\fmeobjects\\python27. I tried to copy the fmeobjectes.pyd to my python Lib folder like you mentioned in your post above but I get an error like this,
"ImportError: DLL load failed: %1 is not a valid Win32 application"
+19How about installing FME 64bit version and using its "fmeobjects.pyd"? You can install both FME 32bit and FME 64bit into different folders of the same machine.
