I have build up the WebAPP of this Project on Mac OS using conda and tensorflow v0.12.1. It work so well still I try to train, tensorflow show this error message:

I use TF1.7.0 instead of TF0.12.1, and fix this problem. But I still don't know what happen in TF0.12.1.

I am struggling to utilise TensorFlow within Jupyter notebook. I have installed TensorFlow via Anaconda Prompt (running as admin). But when I go to call it in my notebook I get the following error string (sorry this is long).
Any help or thoughts would be welcomed here - should I run a full uninstall and try again?
kind regards
Jack

I installed pgadmin4 (v4.4) package with from official Arch Linux package repository. It worked until the most recent update. Now I am not able to add a new server. In the browser I got the error:

I wonder if whether it is only me because I didn't get anything from google search.
I have the same issue psycopg2 2.8.1. Downgrade to 2.7.7 makes the trick.
pgAdmin4 team has released the new version pgadmin4 (v4.5) which will work with latest version of psycopg2 which is psycopg2 2.8.1
https://www.pgadmin.org/download/
Bug: https://redmine.postgresql.org/issues/4143
In my case, first attempt of execution of command /usr/pgadmin4/bin/setup-web.sh showed below error that caused the web URL to show 500 error.
/usr/pgadmin4/bin/setup-web.sh: line 87: semanage: command not found
I'm using AlamLinux. I installed the required package and ran setup-web.sh again to make the web URL working

I want to create a program in pythonista that can control the web browser. I know Selenium is the best for this but I have tried it on pythonista for my iOS iPhone and I get an error.
This is the code:
from selenium import webdriver
browser = webdriver.Chrome()
browser.get('http://www.yahoo.com')
Here is the error:
PermissionError: [Errno 1] Operation not permitted

...implies that the ChromeDriver was unable to create a desired new resource e.g. logfile while initializing a new WebDriver and Web Client session.
As per the discussion Pythonista - Limitations due to iOS following are some of the limitations while using Pythonista :
No fork/exec for new processes. Impacts the subprocess module.
Due to missing fork, no full cleanup of process resources (memory, threads, file handles).
No file access outside of application directory.
No /dev/null and other special files.
Limited processing power of devices (compared to typical PC/Mac).
Process usually is stopped/killed after a while.
An simple example is as follows :
>>> import subprocess
>>> subprocess.call(["ls", "-l"])

What's wrong in your usecase
There can be 2 issues as follows :
When you invoke the following line of code :
browser = webdriver.Chrome()
The ChromeDriver tries to create/modify/access the scoped_directory within the file system. For example on Windows OS :
"chromedriverVersion": "2.35.528161 (5b82f2d2aae0ca24b877009200ced9065a772e73)",
"userDataDir": "C:\\Users\\username\\AppData\\Local\\Temp\\scoped_dir5188_12717"
Possibly ChromeDriver is unable to perform this task/method/functionality.
Again when you invoke the following line of code :
browser = webdriver.Chrome()
As per selenium.webdriver.chrome.webdriver ChromeDriver tries to create a logfile within the file system as per the constructor as follows :
class selenium.webdriver.chrome.webdriver.WebDriver(executable_path='chromedriver', port=0, options=None, service_args=None, desired_capabilities=None, service_log_path=None, chrome_options=None)
Possibly ChromeDriver is unable to perform this task/method/functionality,
Due to the above mentioned reasons you are seeing the error :
PermissionError: [Errno 1] Operation not permitted
Solution
Incase of any of the above mentioned cases the solution would be to restrict the access/creation of the resources within the application directory only.
I'm trying to run headless selenium and to get to grips with it I've set up a new droplet on Digital Ocean (Ubuntu 16).
I am following this tutorial but I'm getting the following error when I run the script.

What should I do? Thanks for your help.
Download the gecko driver from https://github.com/mozilla/geckodriver/releases/tag/v0.11.1
export PATH=$PATH:/loaction of the downloaded geckodriver
Run your Code.
If you get the following Exception
selenium.common.exceptions.WebDriverException: Message: Expected
browser binary location, but unable to find binary in default
location, no 'moz:firefoxOptions.binary' capability provided, and no
bina ry flag set on the command line
Kindly, check the geckodriver and firefox should be of either 32 or 64 bit
Otherwise. Provide the FirefoxBinary path in the code to the FirefoxDriver() using FireFoxBinary Object.
Recently when I tried to restart my buildmaster it failed because of some issues with http.log. I get the following error:

exceptions.IOError: [Errno 22] invalid mode ('r+') or filename: 'E:\\master_dir\\http.log'
I found that my http.log has reached a size of 4GB although it should rotate after 10MB. Why the buildbot was not able to rotate the http.log after 10MB? Why I am getting the error Invalid mode (r+)? Is there a build config parameter to set the rotate size for http.log?
Deleting the file atleast solved the problem of starting buildmaster but I am still clueless why I got this error at the very first place.
I am running buildbot version 0.8.8
Thanks.
EDIT
As asked by djmitche, I tried with twisted logging module. It was logging fine, irrespective of the order of slashes.
######## TWISTED ##########
from twisted.python.logfile import LogFile
LOG_FILENAME_TWISTED = r'C:\wp\log_rotate_twisted.log'
lf = LogFile.fromFullPath(LOG_FILENAME_TWISTED, rotateLength=20)
# Log some messages
for i in range(20):
lf.write('i = %d' % i)
This may be an issue with Twisted Python (and I've proposed adding the corresponding tag).
Can you verify that the log rotation parameters are set correctly, perhaps by patching C:\Python27\lib\site-packages\buildbot-0.8.8-py2.7.egg\buildbot\status\web\baseweb.py in _openLogFile to print rotateLength? The printed output will appear in twistd.log when you restart the master.
