The tests for the schemas should actually still work as long as the schema format doesn't change. (It shouldn't need to.)

umesh-timalsina · 2020-08-04T19:47:46Z

@brollb I am requesting your review in this PR. I will commit the JSON files once other issues are resolved in this PR.

1. Remove keras from requirements (use tensorflow.keras) 2. Fix code generation logic and test cases 3. Minor changes in layer names in test fixtures

umesh-timalsina · 2020-08-18T21:47:50Z

With every test passing with increased timeouts, I think this PR is ready to be reviewed/merged. Would any changes to deepforge be necessary @brollb ?

brollb

At a glance, it looks pretty good! I didn't quite have time for a full review but wanted to let you know my thoughts after skimming the code.

Do you know why the test timeout needed to be increased?

I will play with it tomorrow and see if I have any more comments!

environment.worker.yml

-    - keras==2.2.5
+    - tensorflow==2.3.0
    - pillow
    - dill


Is dill still needed? This might be able to be split out into its own PR but it is hard to say for sure since we don't want it in a broken state :/

Not sure if this file is being used:

            }
            type = arg.type;
-            layer = this.getLayerSchema(layer.base);
+            layer = layer.name !== layer.base ? this.getLayerSchema(layer.base) : undefined;


Is this still necessary? This was required before because we were parsing the source and had to reconstruct the inheritance chain to determine the type info for a given argument. Since the current version parses the argument type from the runtime, we shouldn't need to reconstruct this (and I don't know that it actually helps us at all).

When I try to update the keras project seed, I see the following error:

brollb · 2020-08-19T17:57:20Z

After looking at it a bit more, it looks like this could be an issue with the JSONImporter as an attribute was updated to no longer be an enum. However, I am not sure if this attribute should be changed. Is scale for BatchNorm still a boolean?

umesh-timalsina · 2020-08-25T16:57:22Z

CreateKerasMeta passes when starting with base seed. However it fails during update of the keras seed.

brollb · 2020-08-25T19:23:00Z

I have a couple fixes that should help with some of those errors (#189 #187)

brollb · 2020-08-27T19:48:09Z

I almost forgot that we will need to update initCode.py: https://www.tensorflow.org/guide/keras/save_and_serialize

I almost forgot that we will need to update initCode.py: https://www.tensorflow.org/guide/keras/save_and_serialize

Do we want to save the model in pb format now?

umesh-timalsina · 2020-08-28T18:44:11Z

It appears that TimeDistrubuted layer doesn't add a pointer to a layer for its layer attribute. However, BiDirectional correctly points to the layer using this branch.

init_code.py

-    import os
-    from os import path
-    import time
    tmp_dir = infile.name + '-tmp-' + str(time.time())


Why hasn't this been removed, too?

This will make sure there are no conflicts in the SavedModel directory. i.e. deserializing two models in the same directory can cause problems.

brollb

I left a couple minor comments about the serialization but other than that, it looks good! Nice work.

While converting the test project seed to use this branch for Sequence 2 Sequence Model (specifically when combining 2 states to one between 2 LSTMS as shown in the figure below:

I got the following error:

Connection.js:76 Uncaught (in promise) TypeError: dims.map is not a function
    at Connection.setDimensionality (Connection.js:76)
    at KerasArchEditorWidget.js:402

    at KerasArchEditorWidget.showAnalysisResults (KerasArchEditorWidget.js:395)
    at KerasArchEditorControl.getLatestAnalysis (KerasArchEditorControl.js:963)

brollb · 2020-09-23T18:27:05Z

Can you share the JSON representation of dimensionality/error info?

umesh-timalsina · 2020-09-23T18:35:58Z

The variable dims seems to be a single integer in this case.
