Can I ask you for a piece of code that causes this error? If you don't want to share it publicly, please send a PM.

I think you forgot the parentheses calling the clearAllEvidence function.

Change this code:
net$clearAllEvidence

to this code:
net$clearAllEvidence()

in your script. Clearing the evidence in the network that I got in PM works as intended - after calling clearAllEvidence, the contiguous node ...

Are you using rSMILE 2.0.10? There were changes between this version and previous ones that could affect the results when using various Virtual Evidence methods.

Also - can I ask you to share the xdsl file by email or in a private message on the forum? I tried to replicate this behavior with ...

Note that:

• evidence is not cleared after updateBeliefs
• the node value has a 'valid' flag, which can be checked with isValueValid
• setting or clearing the evidence invalidates the value of the node
• node values are valid when updateBeliefs is successful

Could you please share the code that doesn't work? If you don't want to share it on the forum, you can email me at piotr@bayesfusion.com

Code below works fine with rSMILE 2.0.10

net <- Network()
handle <- net$addNode(net$NodeType$CPT)
net$setNodeDefinition(handle, c(0.2, 0.8))
net$updateBeliefs ...

You cannot use the printNodeInfo function from Tutorial 3 to print non-CPT node values without any modification.
See Tutorial 7 (Continuous model) and Tutorial 8 (Hybrid model). There are examples of how to create, modify and read values from Equation nodes.

I guess using net$getNodeValue is not the best course of action, as there is no value set after I clear the evidence, right?

Yes, you have to call net$updateBeliefs before getting node values.

ClearEvidence function should work on chance nodes. Can you share the code you think is not working?

At this moment BayesMobile is not able to change the definition of the network, which includes observations, strengths and diagnostic faults.
You can modify your network in GeNIe or with SMILE and then load it to BayesMobile.

We had a problem with our pip server.

Try code below again - now it should work.

This is my mistake in the previous post - use write_file method on unrolled property.

You can set Background Knowledge before calling learn method of chosen algorithm.


...
bkk = pysmile.learning.BkKnowledge()
bkk.match_data(self.ds)
bkk.add_forbidden_arc("node_id", "outcome_id")
bkk.add_forced_arc("node_id", "outcome_id")
baySearch.set_bk_knowledge(bkk)
net = baySearch.learn(self ...

UnrollResults contains unrolled PyNetwork and mapping (an array). You can simply save unrolled network by write_file method call e.g.

Probably the directory where you opened the Python Interpreter is different from where you have the xdsl file, so you get the error code responsible for the missing file. Try to open the Interpreter in the folder with the xdsl file, or enter the absolute path when reading the file (net.read_file ...).

Remove self from create_cpt_node arguments.
Also - I can't see print_all_posteriors function declaration. You have to copy that function from our tutorial.
