kandi X-RAY | ETM Summary
This is code that accompanies the paper titled "Topic Modeling in Embedding Spaces" by Adji B. Dieng, Francisco J. R. Ruiz, and David M. Blei. (Arxiv link: ETM defines words and topics in the same embedding space. The likelihood of a word under ETM is a Categorical whose natural parameter is given by the dot product between the word embedding and its assigned topic's embedding. ETM is a document model that learns interpretable topics and word embeddings and is robust to large vocabularies that include rare words and stop words.

QUESTION
I have the following XML returned by an API:
...ANSWER
Answered 2022-Mar-22 at 16:36There is one problem with this XML sample: it contains a HTML entity ° that is not a valid XML entity. The contents of should probably be wrapped in a CDATA object.
If you fix that, you can register the ns3 namespace and use XPath to get to the entities:
QUESTION
I have a playbook that is launched from AWX with machine credentials, ie. with ssh_user_A. In this playbook, i need to perform a couple of tasks with another SSH user, ie. ssh_user_B.
In terms of credentials, I have:
- machine credentials for
ssh_user_Athat are OK, I can do whatever I need - a public/private keys couple for
ssh_user_B:- the public key is present on the remote host in the
~ssh_user_B/.ssh/authorized_keysfile - if I test this public/private key with a temp machine credentials (not possible in final target) and a dummy playbook or an ad-hoc module call, it works I can do whatever I need
- the public key is present on the remote host in the
I change the SSH user in the playbook with these instructions:
...ANSWER
Answered 2022-Mar-02 at 08:54I've made a lot of tests and found the problem: by default, to connect to the target hosts, Ansible uses the smart connection plugin. In my case, the smart plugin leads to the use of the native OpenSSH.
Forcing manually the use of the paramiko connection plugin solves the problem, everything is OK (paramiko is a Python implementation of OpenSSH). Just need to add the instruction connection: paramiko at the needed level:

I have ec2 instance with ubuntu v20.04 and it has python v3.8.10 and pysftp 0.2.9.
I have generate .pem file from .ppk file using below command

I am able to connect successfully to sftp server using command line-
...ANSWER
Answered 2022-Jan-28 at 09:18The error comes form underlying Paramiko and is discussed here:
Paramiko authentication fails with "Agreed upon 'rsa-sha2-512' pubkey algorithm" (and "unsupported public key algorithm: rsa-sha2-512" in sshd log)
Though pysftp does not expose the disabled_algorithms parameter.
You better switch to using Paramiko directly. The pysftp is abandoned project. See pysftp vs. Paramiko.
QUESTION
I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):
encountered RSA key, expected OPENSSH key
Executing the same command from the system shell (using the same private key of course) works perfectly fine.
On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:
userauth_pubkey: unsupported public key algorithm: rsa-sha2-512
Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.
It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

...ANSWER
Answered 2022-Jan-13 at 14:49Imo, it's a bug in Paramiko. It does not handle correctly absence of server-sig-algs extension on the server side.
Try disabling rsa-sha2-* on Paramiko side altogether:
QUESTION
I am trying to use pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git to install a custom-made python package (shared by multiple applications) from BitBucket WITHOUT having to enter the SSH password.
There seems to be a lot of good information in one of the answers to this question for doing this in GitLab, etc. There's also some solid supporting information here.
I've already setup an SSH key between my local Mac and this BitBucket account. I'm able to push/pull code all the time to/from this account without having to re-enter the SSH password. Why is the pip install command requiring the password, when it's not required by git commands? Is there a way around this with BitBucket and the setup I've described?
When I run the GIT_SSH_COMMAND='ssh -vvv' pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git command recommended in the comments, I get the following (sanitized) response:
ANSWER
Answered 2021-Nov-21 at 02:34Your log does not show SSH require a password. But a passphrase (because the private key was created and then stored encrypted, protected by a passphrase).
That means any pip install should be done from a shell where eval $(ssh-agent); ssh-add ~/.ssh/id_rsa has been executed first, in order to cache said passphrase, and allow the all process to not require any input, for an unattended run.

I am very new to AWS ec2, using linux, and using scp commands, just to get that out of the way. I have an AWS ec2 instance set up and want to upload a python file to that instance using an scp server command.

Answered 2021-Sep-25 at 23:33Ultimately you're getting caught up in a directory name that has a space character in it. As you can see:
Warning: Identity file C:/Users/Mason not accessible: No such file or directory.
Note that the command is broken where your name has a space in it. To overcome this run:
QUESTION
My scenario is that I have a Spring Integration Flow with a SftpInboundAdapter which shall get a file from a SftpServer "myHost". The file contains JSON which is to be converted into MyEvent entities to be forwarded to further processing. The process is implemented in a task scheduled by Spring Scheduler. Therefore the Integration Flow is not to start automatically with the Application having that autoStartup(false).
The Spring Integration Flow is:
- testSftpSessionFactory: to provide the session to the SFTP server
- testSftpInboundAdapter: to get the SFTP remote file
- sftpInputChannel: a Publish-Subscribe channel to have multiple message consumers
- sftpInputChannel-MessageHandler: to get the JSON content of the file transformed
- deleteLocalFileService-MessageHandler: to delete the remote file after successful processing
- controlChannel: to send Integration Flow control commands
- controlChannel-ExpressionControlBusFactoryBean: to start the testSftpInboundAdapter
The types TransferContext, TransferChannel and MyService are Java classes of mine with some fields fed from YAML properties which provide values for the sftpSessionFactory as host, port, user, password and the sftpInboundAdapter as remoteDirectory, remoteFilename, preserveTimestamp, localDirectory, etc. The Service is to process the MyEvent entities.
These are my SI beans:
...ANSWER
Answered 2021-Sep-20 at 13:25Since you say that both tasks starts on the same thread, then it looks like you deal with the latest Spring Boot: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#features.spring-integration. When Spring Integration now relies on the auto-configured TaskScheduler which comes with one thread in its pool.
You can change that configuration, or your can add a task-executor to the poller of your sftpInboundAdapter Inbound Channel Adapter definition: https://docs.spring.io/spring-integration/docs/current/reference/html/messaging-endpoints.html#taskexecutor-support. This way a real job is going to be shifted from a scheduler thread to one provided by that executor.

QUESTION
I was using the exact private key sucessfully for 2 weeks to ssh into my EC2 instance. I tried today (without any changes from my side) and it is not working anymore...
Full verbose logs are as below: (where replaced all ip occurences with $IP) Facts:
- ip is up and running, webserver is returning serving the page fine so instance is not stopped
- i made no manual changes in last 2 weeks to cause this issue
- Before 2 months I changed the ssh key by adding in known keys in ec2 instance the current key. I added it to user ubuntu at
.ssh/authorized_keys. It worked correctly for 3 weeks and since then instance is not restarted/stopped
ANSWER
Answered 2021-Aug-02 at 08:06Based on the comments.
Since normal ssh connections did not work, it was possible to connect to the EB instance using web ssh (instance connect) or ssm session manager. This allowed to update ssh authorized_keys file.
The instance could be replaced by AWS due to scaling events, AZ rebalancing or the physical hardware issues. In this cases, custom changes to the instance would be erased. To overcome this, need to use custom AMI.
