My reason is that after installing VM virtual machine, the network connection of the computer does not have VM1 and VM8, and then according to the added link description

After tensorflow installation, an error occurred while importing: importerror: DLL load failed: the specified module could not be found
(author: Chen freebie)

Tensorflow can be installed via PIP or anaconda, but once installed, it runs in a Python script
import tensorflow as tf
ImportError: DLL Load failed: : It failed to find the specified module.
Three solutions were tried:
1) Besides TensorFlow, tensorFlow-GPU should be installed
Later, I learned that the tensorFlow-GPU was installed mainly for acceleration, and the installation did not solve this problem.
2) The second is to uninstall and reinstall
So I upgraded the PIP, uninstall tensorflow by PIP uninstall tensorflow, and then reinstall it by PIP install tensorflow, but still couldn’t solve the problem.
3) Three said to update the pillow
Pillow is an image processing library in Python, which comes with Anaconda. But maybe because Pillow’s version is older, you need to update it.
conda uninstall pillow
conda update pip
pip install pillow
Through the above three lines of commands, first uninstall the PILLOW in Anaconda, then update the PIP, and then install the latest PILLOW through the upgraded PIP. The problem is solved. Hey, it is also amazing that the Python package conflicts with TensorFlow… However, the installation of strange problems are mostly version problems, can only check the version, but most of the time is to upgrade, and sometimes to downgrade is more headache.

The following will make transformations to your Kibana index. It is recommended you backup your Kibana index prior to running any of the following commands.
In order to migrate to Kibana 6, your Kibana index needs to be reindexed. This will make transformations to the data model, removing types which are being removed in Elasticsearch.
A UI is available in X-Pack 5.6 to assist with the migration. The following is provided should you be required to run the migration manually. The commands assume you’re using the default . kibana index, without an alias. If kibana. index is set to something different in your kibana. yml, or you’re using an alias, you will need to modify the commands.
To perform this migration without downtime, you will need to be running Kibana 5.6. This is the only version which supports both of the index types. When running 5.6, add "index. format": 6 and "index.mapping. single_type": true under settings in the second step to ensure additional types will not be added after migrating.

Installing Windows Identity Foundation on Windows 8 – The Certificate for the signer of the message …
Just a very quick note here, in case you’re struggling to get Windows Identity Foundation installed on your Win8 development machine.
Have you been setting up another development machine for Azure development on Windows 8, and have run into a problem installing the Windows Identity Framework? Yeah, me too. The error message is “Windows Update Standalone Installer. Installer encountered an error 0x80096002. The certificate for the signer of the message is invalid or not found.”
The short answer is that WIF is managed on Windows 8 using the “Turn Windows Features On and Off”. You can get that by:
1. Punch that Windows key!
2. Type “Windows Features” and make sure you’ve chosen to search “Settings” from the search pane.
3. Click on “Turn Windows features on or off”
4. Check the box next to “Windows Identity Framework 3.5” (and yes, this supports .NET 3.5 and 4.0 applications).
5. Press “OK” and let setup do it’s thing.
You’re welcome!

Pandas memory error
Problem description
I will use pandas to process data, which is known to all children’s shoes related to data processing. Read in from CSV file with a pd.read_csv, and then play as you like. Recently, when I was doing data preprocessing, I encountered a headache. Every time the program was executed to pd. Read_csv is always reported to memory error. Finally all kinds of search stackoverflow, finally find the crux:
Replace Python with X64
Yes, it’s as simple as that!
Attached to the
As anyone who has ever used Pandas knows, it is impossible to install Pandas in WIN without any trouble. With all kinds of dependence and the disgusting network in China, it may not be so easy to change Python into X64. Please don’t be impatient, and here comes the magic device:
Please use Anaconda, select an X64, download and install it directly, graphically, install the python X64 version with a full set of data analysis package, of course, there is a Python X64 version with ipython and other tools, not malicious, and even strongly recommend the first time you install Python directly to use this.
The end

Error code is 2502 / 2503 when installing MSI format installation package under win10 or win8
An error was reported when installing SVN (MSI format) under Win10:
The installer has encountered an unexpected error installing this package.this may indicate a problem with package.the error code is 2502.

finally found that usually in win8 or win10 under the installation of msi format package may appear when the error.
this is the permission problem of the system, the solution is as follows:
1. Combine the keys win+x and select “command prompt (administrator)”
2, run command: msiexec /package “install package path”
