Pywt is not importing _cwt module correctly when the program is compiled with Pyinstaller. I verified that _cwt.py is present in my pywt root (in site-packages on the path) and _cwt.pyd is in the pywt\_extensions dir. I can successfully import pywt from Python. Below is a minimum (non) working example to illustrate the ImportError traceback.
Program pywt_test.py
# -*- coding: utf-8 -*-
try:
import sys, traceback
import pywt
print pywt.__version__
except ImportError:
type_, value_, traceback_ = sys.exc_info()
e_msg = traceback.format_exception(type_, value_, traceback_)
with open('pywt_error_log.txt','w') as f:
f.write(''.join(e_msg))
Pyinstaller spec file pywt_test.spec
# -*- mode: python -*-
block_cipher = None
a = Analysis(['pywt_test.py'],
pathex=['C:\\Users\\user', 'C:\\Users\\user'],

win_no_prefer_redirects=False,

a.scripts,

Pyinstall compile command: pyinstaller pywt_test.spec.

ImportError: No module named _cwt
I tried adding _cwt to the pathex, hiddenimports, etc. None change the error.
How can I get _cwt, and the entire pywt package, to load with Pyinstaller?
Versions, for reference:
Just add it to the hidden imports:
...
hiddenimports=['pywt._extensions._cwt'],
...
