PyInstaller+Tensorflow+Sonnet

General Discussion

#1

I’m having issues building tensorflow+sonnet applications with pyinstaller. I’ve built keras ones fine, but sonnet ones have an issue as below.

Sonnet doesn’t seem to work with pyinstaller. This can be reproduced with a very simple example as below:

import sonnet
print(“Hello world”)

I used a spec file:

-- mode: python ; coding: utf-8 --

The following fixes a different pyinstaller issue due to recursion

import sys
sys.setrecursionlimit(5000)

block_cipher = None

a = Analysis([‘pi_test.py’],
pathex=[‘c:\Software\ICServer\ICServer-src\Python\GraphNet\minimal_pyinstaller_test’],
binaries=[],
datas=[],
hiddenimports=[],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher,
noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
exe = EXE(pyz,
a.scripts,
[],
exclude_binaries=True,
name=‘pi_test’,
debug=False,
bootloader_ignore_signals=False,
strip=False,
upx=True,
console=True )
coll = COLLECT(exe,
a.binaries,
a.zipfiles,
a.datas,
strip=False,
upx=True,
upx_exclude=[],
name=‘pi_test’)

The error is:

I reported this to the sonnet developers and the closed the issue straight away saying it wasn’t their problem and I should report it to tensorflow developers

Sonnet is written in pure python, and the method in question (in src/batch_norm.py) is decorated with @utils.smart_autograph. Can anyone suggest how to get this working?

Thanks

#3

Is this a gast version issue?

#4

The gast error looks like a historic thing (and not quite the same error) “On TensorFlow 2.2 or higher, the gast bug has been fixed and gast 0.3+ would be required.”. I’m using tensorflow 2.4 and gast 0.3.3. If I attempt to update gast to the latest version it breaks tensorflow even from the python interpreter.

The error I see is only with pyinstaller, and relates to autograph not being able to access the BaseBatchNorm call (or possibly code within this?) method once packaged.

Have you tried to use the pyinstaller Tensorflow hooks with a supported version?

#7

Thanks, I got it working with that hook. Two futher changes were also required:

i) I had to change the line in the hook:

datas = collect_data_files('tensorflow', excludes=data_excludes)

to:
datas = collect_data_files(‘tensorflow’)

as excludes dosn’t seem to be in the API (at least for versions I have Python: 3.8.3, Pyinstaller 3.6)

ii) I had to add the following import to my python file:

import tensorflow.python.keras.engine.base_layer_v1

Thanks a lot!
