Tensorboard应该从commnad行开始:
tensorboard --logdir=path
我需要从代码中运行它。到现在为止我用这个:
import os
os.system('tensorboard --logdir=' + path)
但是,由于未包含在系统路径中,因此张贴板无法启动。我在Windows上使用PyCharm和virtualenv。我不想改变系统路径,因此唯一的选择是从virtualenv运行它。这该怎么做?

答案可能有点晚了,但这对我来说在Python 3.6.2中是有用的:
import tensorflow as tf
from tensorboard import main as tb
tf.flags.FLAGS.logdir = "/path/to/graphs/"
tb.main()
使用默认配置运行tensorboard,并在" / path / to / graphs /"中查找图表和摘要。您当然可以使用以下命令更改日志目录并设置任意数量的变量:
tf.flags.FLAGS.variable = value
希望它有所帮助。

您应该在单独的帖子中启动tensorBoard
:
def launchTensorBoard():
import os
os.system('tensorboard --logdir=' + tensorBoardPath)
return
import threading
t = threading.Thread(target=launchTensorBoard, args=([]))
t.start()

当我遇到同样的问题时,您可以使用受tensorboard\main.py
启发的以下行:
from tensorboard import default
from tensorboard import program
tb = program.TensorBoard(default.PLUGIN_LOADERS, default.get_assets_zip_provider())
tb.configure(argv=['--logdir', my_directory])
tb.main()
使用my_directory
作为您要检查的文件夹。如果您要避免在tb.main()
之后被阻塞,请不要忘记创建单独的线程。
最好的问候
编辑Tensorboard V1.10:
出于某些个人原因,我用另一种方式写它:
class TensorBoardTool:
def __init__(self, dir_path):
self.dir_path = dir_path
def run(self):
# Remove http messages
log = logging.getLogger('werkzeug')
log.setLevel(logging.ERROR)
# Start tensorboard server
tb = program.TensorBoard(default.PLUGIN_LOADERS, default.get_assets_zip_provider())
tb.configure(argv=['--logdir', self.dir_path])
url = tb.launch()
sys.stdout.write('TensorBoard at %s \n' % url)
编辑Tensorboard V1.12:
根据Elad Weiss和tsbertalan的张量板1.12版本。
def run(self):
# Remove http messages
log = logging.getLogger('werkzeug').setLevel(logging.ERROR)
# Start tensorboard server
tb = program.TensorBoard(default.get_plugins(), default.get_assets_zip_provider())
tb.configure(argv=[None, '--logdir', self.dir_path])
url = tb.launch()
sys.stdout.write('TensorBoard at %s \n' % url)
然后运行它即可:
# Tensorboard tool launch
tb_tool = TensorBoardTool(work_dir)
tb_tool.run()
这将允许您在不干扰http请求的情况下与主进程同时运行Tensorboard服务器!

对于Tensorboard 2.1.0,这对我有效:
python -m tensorboard.main --logdir $PWD/logs
您必须先激活您的环境。 (就我而言,conda install
出现致命错误,因此我需要通过tf
内的pip
重新安装conda
。)

使用Tensorboard 2 API(2019):
from tensorboard import program
tb = program.TensorBoard()
tb.configure(argv=[None, '--logdir', tracking_address])
url = tb.launch()
注意:tb.launch()创建一个守护进程线程,该线程将在进程完成后自动终止

针对Tensorboard 2(2019)的完整解决方案,并自动打开适用于Windows和Linux的Chrome浏览器。适用于两种环境:conda和virtualenv。 此解决方案会抑制Tensorboard输出,因此不会(恼人地)在stdout中显示
from multiprocessing import Process
import sys
import os
class TensorboardSupervisor:
def __init__(self, log_dp):
self.server = TensorboardServer(log_dp)
self.server.start()
print("Started Tensorboard Server")
self.chrome = ChromeProcess()
print("Started Chrome Browser")
self.chrome.start()
def finalize(self):
if self.server.is_alive():
print('Killing Tensorboard Server')
self.server.terminate()
self.server.join()
# As a preference, we leave chrome open - but this may be amended similar to the method above
class TensorboardServer(Process):
def __init__(self, log_dp):
super().__init__()
self.os_name = os.name
self.log_dp = str(log_dp)
# self.daemon = True
def run(self):
if self.os_name == 'nt': # Windows
os.system(f'{sys.executable} -m tensorboard.main --logdir "{self.log_dp}" 2> NUL')
elif self.os_name == 'posix': # Linux
os.system(f'{sys.executable} -m tensorboard.main --logdir "{self.log_dp}" '
f'--host `hostname -I` >/dev/null 2>&1')
else:
raise NotImplementedError(f'No support for OS : {self.os_name}')
class ChromeProcess(Process):
def __init__(self):
super().__init__()
self.os_name = os.name
self.daemon = True
def run(self):
if self.os_name == 'nt': # Windows
os.system(f'start chrome http://localhost:6006/')
elif self.os_name == 'posix': # Linux
os.system(f'google-chrome http://localhost:6006/')
else:
raise NotImplementedError(f'No support for OS : {self.os_name}')
初始化:
tb_sup = TensorboardSupervisor('path/to/logs')
完成培训/测试后:
tb_sup.finalize()

要在指定的虚拟环境中从python脚本运行tensorboard,您必须将tensorboard
更改为/path/to/your/environment/bin/tensorboard
。还建议按照@Dmitry的建议在单独的线程中执行命令。
看起来像这样,并且可以在tb和tf 1.14.0版中使用:
def run_tensorboard(logdir_absolute):
import os, threading
tb_thread = threading.Thread(
target=lambda: os.system('/home/username/anaconda3/envs/'
'env_name/bin/tensorboard '
'--logdir=' + logdir_absolute),
daemon=True)
tb_thread.start()

从TensorBoard版本1.9.0开始,以下操作可在同一Python进程中以默认设置启动TensorBoard:
import tensorboard as tb

tb.program.FLAGS.logdir = 'path/to/logdir'
tb.program.main(tb.default.get_plugins(),
tb.default.get_assets_zip_provider())

以下内容将打开Chrome标签并启动TensorBoard。只需提供所需的目录和您的系统名称。

os.system(
"cd <directory> \
&& google-chrome http://<your computer name>:6007 \
&& tensorboard --port=6007 --logdir runs"
)

如果您的python解释器路径为:
/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/bin/python3.6
您可以运行此命令代替tensorboard
/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/bin/python3.6 /usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/版本/3.6/lib/python3.6/site-packages/tensorboard/main.py
对我有用。

有相同的问题: 在Windows上工作时,您可以使用批处理文件来完全自动打开张量板,如下面的示例所示。
您可能想在可见的控制台窗口(cmd.exe)中打开tensorboard。在IDE(pycharm)中调用一个批处理文件将在IDE中运行它,因此在后台运行,这意味着您看不到控制台。因此,您可以使用一种解决方法:调用一个批处理文件,然后调用该批处理文件以启动tensorboard。
注意:在本示例中,我使用Anaconda作为虚拟环境
batch_filename = 'start_tb.bat' # set filename for batch file
tb_command = 'tensorboard --logdir=' + log_dir # join strings for tensorflow command
# creates batch file that will call seconds batch file in console window (cmd.exe)
with open(os.path.join('invoke.bat'), "w") as f:
f.writelines('start ' + batch_filename)
# created batch file that activates Anaconda environment and starts tensorboard
with open(os.path.join(batch_filename), "w") as f:
f.writelines('\nconda activate YOURCondaEnvNAME && ' + tb_command) # change to your conda environment, or other virtualenv
# starts tensorboard using the batch files (will open console window)
# calls the 'invoke.bat' that will call 'start_tb.bat'
os.system('invoke.bat')
# starts tensorboard in default browser >> ATTENTION: must be adapted to local host
os.system('start "" http://YOUR-COMPUTER-NAME:6006/') # just copy the URL that tensorboard runs at on your computer
有时候,您可能需要刷新浏览器中的张量板,因为张量板在正确设置之前就已经打开。

尝试从python
运行import os
os.system('python -m tensorflow.tensorboard --logdir=' + path)
在PyCharm中为我工作(但在linux上,所以如果shell语法不同,那么你必须调整它)
