Error after installation via pip

[bradkyle]

I have recently attempted to install tensorboard via pip as detailed in the README.md. The installation was deemed successful however when I try to run tensorboard after the installation, I keep on receiving an import/ undefined symbol error as seen below.

`Traceback (most recent call last):

I am using Version: 1.0.0a6

Have I missed something in the installation process?
What can I do to fix this?

Thanks

Could you tell me the version? Is it 1.0.0a6 or 1.0.0a7? In general it's already usable after pip install tensorboard

[bradkyle]

Hi, thanks for the response.
I am currently using Version: 1.0.0a6
and I got the error immediately after running sudo pip install tensorboard

[zihaolucky]

@bradkyle Could you try to build from source? Seems the wrapper doesn't build correctly in Python3.5 python/_pywrap_tensorflow.so: undefined symbol: PyBytes_AsStringAndSize

[Hskye]

Maybe you can try sudo pip install tensorflow.tensorboard.

Hi, I am facing the same issue.
@Hskye, I tried installing tensorflow.tensorboard but it throwing this error:
Exception:

I am using python 3.5 and I installed tensorflow from pip3.

Thanks in advance.

Hi all,
I'm facing the same issue. Also, Python 3.5.

Hi! Same issue here. Symbol not found: _PyBytes_AsString

Edit: Found a solution! Access tensorboard through your site-packages dir (I have tf globally installed)
python /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/tensorflow/tensorboard/main.py --logdir=./logs

Hi all,
I'm facing the same issue. Also, Python 3.5.

Hi, I'm having the same issue with python 3.4.3 on Ubuntu 14.04.5 LTS.
The trick supposed by @daxaxelrod helped, for me it's:

python3 /usr/local/lib/python3.4/dist-packages/tensorboard/main.py --logdir=./logs 

[xiaoschannel]

same issue, python3.5.4, tensorboard a6, WSL. Installing tensorflow.tensorboard instead of tensorboard works fine.

It looks like the issue is related to finding the python executable in the wrapper script (/usr/bin/tensorboard, line 48):

return SearchPath('python')

On systems where there is a default python2 installation, this will load python2, even if you have python3 installed (often called python3). When I print out args just before the try block on line 139 it returns:

['/usr/bin/python2.7', '/usr/lib/python3.4/site-packages/tensorboard/tensorboard.runfiles/org_tensorflow/tensorflow/tensorboard/tensorboard.py']

If I alter line 48 to search for python3 (instead of python), then tensorboard runs without issue.
