我正在嘗試使用Tensorflow和Pyinstaller制作我的Python代碼的可執(zhí)行文件.可執(zhí)行文件生成正確,但當(dāng)我嘗試運(yùn)行它時(shí),我收到以下錯(cuò)誤：

[11241] Failed to execute script detection_init

如果仔細(xì)觀察,Pyinstaller期望文件_checkpoint_ops.so在目錄tensorflow / contrib / util / tensorflow / contrib / framework / python / ops /中,但是沒(méi)有這樣的目錄. _checkpoint_ops.so位于tensorflow / contrib / framework / python / ops /.如何糾正這個(gè)錯(cuò)誤？

解決方法:

將以下內(nèi)容添加到spec文件中(找到tensorflow二進(jìn)制文件并將它們添加到主二進(jìn)制文件目錄中的.app)：

import os

tensorflow_location = '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/tensorflow'

tensorflow_binaries = []

for dir_name, sub_dir_list, fileList in os.walk(tensorflow_location): 
  for file in fileList:
    if file.endswith(".so"):
      full_file = dir_name   '/'   file
      print(full_file)
      tensorflow_binaries.append((full_file, '.'))

確保還將二進(jìn)制文件添加到Analysis

a = Analysis(...,
             binaries=tensorflow_binaries,
             ...)

并確保.exe / .app版本中包含二進(jìn)制文件.這是一個(gè)簡(jiǎn)單的例子：

pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          name='TestApp',
          debug=True,
          strip=None,
          upx=True,
          console=True, icon='Test.icns')
app = BUNDLE(exe,
    a.scripts,
    a.binaries,
    a.zipfiles,
    a.datas,
    name='Test.app',
    icon='Test.icns',
    bundle_identifier='com.Test.TestApp',
    info_plist={
        'NSHighResolutionCapable': 'True'
            },
    )

您需要做的最后一件事是修改tensorflow load_library.py文件以指向.app運(yùn)行時(shí)期間二進(jìn)制文件的相對(duì)路徑.

該文件通常位于此處(相對(duì)于python安裝)：site-packages / tensorflow / python / framework / load_library.py

您需要添加resource_path函數(shù)并修改load_op_library函數(shù)以將file_name指向相對(duì)路徑(并忽略按子文件夾查找二進(jìn)制文件).

def resource_path(relative_path):
    """Due to pyinstaller changing root dir of project filenames need to be processed in order to open properly

    Parameters
    ----------
    relative_path : str
        String containing filename of project item (ex: models/bladder...h5)

    Returns
    -------
    path : str
        path relative to .exe on local computer
    """
    import sys
    import os

    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    path = os.path.join(base_path, relative_path)
    return path

def load_op_library(library_filename):
  """Loads a TensorFlow plugin, containing custom ops and kernels.

  Pass "library_filename" to a platform-specific mechanism for dynamically
  loading a library. The rules for determining the exact location of the
  library are platform-specific and are not documented here. When the
  library is loaded, ops and kernels registered in the library via the
  `REGISTER_*` macros are made available in the TensorFlow process. Note
  that ops with the same name as an existing op are rejected and not
  registered with the process.

  Args:
    library_filename: Path to the plugin.
      Relative or absolute filesystem path to a dynamic library file.

  Returns:
    A python module containing the Python wrappers for Ops defined in
    the plugin.

  Raises:
    RuntimeError: when unable to load the library or get the python wrappers.
  """ 
  # REMOVE AFTER PYINSTALLER USE
  library_filename = resource_path(library_filename.split('/')[-1])

這將使tensorflow通過(guò)pyinstaller應(yīng)用程序的相對(duì)路徑獲取二進(jìn)制文件(參見(jiàn)：https:///PyInstaller/runtime-information.html#run-time-information).

然后,Tensorflow將獲取由.spec文件打包的二進(jìn)制文件.

記得在Pyinstaller打包后取消注釋load_library.py中的library_filename = resource_path(library_filename.split(‘/’)[ – 1])行(否則Tensorflow在你的本地Python環(huán)境中運(yùn)行時(shí)將無(wú)法找到二進(jìn)制文件！ )
