Failed import of cbook due to upgrade to matplolib 2.1.2

[Massi]

Hi everyone,

I've currently upgraded matplolib version of my software (on Windows 10, python 2.7) from 1.4 to 2.1.2 and now when I try to freeze it via PyInstaller (3.3.1) I get the following error:

  File "MyProg.pyw", line 19, in <module>

ImportError: cannot import name cbook

I've also tried to include it in my hidden_import list:

# -*- mode: python -*-

block_cipher = None

a = Analysis(['../MyProg.pyw'],

             pathex=[HOMEPATH],

             binaries=None,

             datas=None,

             hiddenimports=['pymysql', 'pg8000', 'matplotlib.cbook'],

             hookspath=[],

             runtime_hooks=[],

             excludes=[],

             win_no_prefer_redirects=False,

             win_private_assemblies=False,

             cipher=block_cipher)

Still I get the same error... any advice?

Just for the record here is the line that seems to bother PyInstaller:

# cbook must import matplotlib only within function

# definitions, so it is safe to import from it here.

from . import cbook

from matplotlib.cbook import (

    _backports, mplDeprecation, dedent, get_label, sanitize_sequence)

Thanks in advance!

Just a clarification, target version of Matplotlib is 2.2.0, not 2.1.2.
