I'm facing this issue while running polymer init on polymer-cli.
Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry'
Possible reasons:
- Element name starts with uppercase alphabet
- Element name does not have a hyphen in it (Thanks to Margherita Lazzarini)
Long story:
I was working with polymer CLI and when I ran polymer init, among the series of options it asks me, one of them was Main element name for which I entered Polymer-test-element.
It was giving me this error :
Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': "Polymer-test-element" is not a valid custom element name
The problem was I had used an uppercase alphabet in the declared element name. So when I replaced 'P' with 'p' it resolved the issue.
Hope this helps you :)
Probably you have defined a Custom Element without a hypen (-) in its name.
See this answer
Check your import, maybe you imported an element with e.g.
<link rel="import" href="../../bower_components/iron-icons/av-icons.html">
instead of
<link rel="import" href="../iron-icons/av-icons.html">
which could both be a valid path but the first one got me the DOMException.

So I am having this problem where I enter data in MySQL table everything works fine it stored in the table and when I read it with the select command it perfectly works but when I close my workbench my all the entries are removed only the null table is there
The most common mistake would be that you are not committing the data. Workbeanch opens a connection that isolates you from the rest of the DB and all your changes are visible only to yourself. When you close the Client (without committing) you end up making a ROLLBACK.
Call COMMIT; see here or click the respective button in the client.
If you do not want to write the command you can use the appropriate buttons:

I was working on CartPole-v0 provided by openai gym. I noticed that my program always resets after 200 steps. If I sum all the rewards from an episode, where the maximum reward is 1.0 for each timestep, I never get more than 200. I was wondering if there is any configuration I might have missed in the gymlibrary gym. Has anybody found this problem?
CartPole-v0 gives a reward of 1.0 for every step your agent is "alive".
The environment is registered with these lines of code:
register(
id='CartPole-v0',
entry_point='gym.envs.classic_control:CartPoleEnv',
max_episode_steps=200,
reward_threshold=195.0,
)
which, in the current version of the repository, can be found here.
That max_episode_steps=200 means that an episode automatically terminates after 200 steps. So, the maximum score you can get is 200.

I would like export result obtained from "Data flow Task" to a "Text" file with "^" delimited format.
But in the Flat file connection manager I don't see that delimiter option. Please suggest. I am okay with any different way of getting the result in the mentioned format through SSIS.
Thanks in advance.
-Manoj Gade
Please try this:
go to Flat File Connection Manager for Your output file. Then go to "Advanced" tab. Select every column aside from the last one (this is important!) and just type ^ in "ColumnDelimeter" property. Drop down list will present You with few suggestions, but still You can type the property malually. Hope that helps!

I have a textbox with the following expression:
=DataSets("MyDataSet").RewrittenCommandText
But nothing is returned, not even error. Any ideas?
The RewrittenCommandText property value is populated at runtime from data extensions that support the IDbCommandRewriter interface. If a data extension doesn't support this interface, RewrittenCommandText will be Nothing. The built-in report model data source supports this interface but I don't think it is supported by many other data extensions.
I just tried a standard SQL Server dataset and RewrittenCommandText returned Nothing even though the SQL is being built by custom DLLs. However, the CommandText returned the generated SQL, not the expression being used to generate the SQL so that might work for you.
