我正在尝试使用Tensorflow和Pyinstaller生成我的Python代码的可执行文件。可执行文件正确生成但是当我尝试运行它时，我收到以下错误：
Traceback (most recent call last):

如果仔细观察，Pyinstaller期望目录_checkpoint_ops.so中的文件tensorflow/contrib/util/tensorflow/contrib/framework/python/ops/，但是没有这样的目录。 _checkpoint_ops.so位于tensorflow/contrib/framework/python/ops/。如何纠正这个错误？
答案 0 :(得分：0)
将以下内容添加到您的规范文件中（找到tensorflow二进制文件并将它们添加到主二进制文件/文件目录中的.app中）：
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, '.'))
确保您还将二进制文件添加到Analysis
a = Analysis(...,
binaries=tensorflow_binaries,
...)
并确保二进制文件包含在.exe / .app版本中。这是一个简单的示例：
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运行时二进制文件的相对路径。
文件通常位于此处（相对于python安装）：site-packages/tensorflow/python/framework/load_library.py
您需要添加resource_path函数并修改load_op_library函数以将file_name指向相对路径（并忽略通过子文件夹查找二进制文件）。
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])
这将使tensorflow通过pyinstaller应用程序的相对路径来获取二进制文件（请参阅：https://pythonhosted.org/PyInstaller/runtime-information.html#run-time-information）。
然后，Tensorflow将获取.spec文件打包的二进制文件。
请记住在Pyinstaller打包后取消注释library_filename = resource_path(library_filename.split('/')[-1])中的load_library.py行（否则Tensorflow在本地Python env中运行时将找不到二进制文件！）
