What tutorial? I recommend following the guidelines in the docs.

[glass iris]

I read the documentation, nothing worked out, and the video on YouTube is from Russia

[onyx flint]

Well, you'll need to provide details on your setup and issues.

Ideally, reset everything and flow the docs. Then if there are still issues, share the info here.

[glass iris]

And of course Download Conda

[onyx flint]

Conda is one of the steps in the docs. But to be honest, it's not a hard requirement. It's just for setting up a virtual environment.

Could also use venv or some other simpler alternative.

What to do

[glass iris]

Can it be fixed?

[onyx flint]

For starters, avoid taking photos. Make it screenshots.

Second, this is not really an error, and honestly it's probably not a problem at all.

I'm not sure if it's fixabale. It seems to be an common bug lately.

[glass iris]

I downloaded everything, but the result is zero

@onyx flint And what is my mistake

[onyx flint]

Share code properly:

Add a comment with a line number if there is an error message.

[onyx flint]

The errors mean that a component or an object having the component was destroyed, yet you still try to access it.

[glass iris]

And what if the object itself exists, but there is a mistake And what if the object itself exists, but the error writes

[onyx flint]

Then you're either looking at the wrong object, or it was destroyed at the time of the error.

You need to use backticks: ```

using Unity.MLAgents;

using Unity.MLAgents.Actuators;

Click one of the errors and share it's details in the bottom.

[onyx flint]

This seems to be thrown by the inspector ui, not your code. I'd assume the Agent script ui specifically. Is there actually an issue with it? Because I think you can just ignore this error.

[glass iris]

Same error, different name.

[onyx flint]

That's the same.

[glass iris]

wrong photo

[onyx flint]

Same.

[onyx flint]

This one is different.

[glass iris]

I still tried to control it, but it didn't work.

[onyx flint]

Seems like an issue with your setup.
I'd try running their sample and see if it works. If it does, then your setup is wrong. Refer to the sample and documentation for the correct setup and code:
https://docs.unity3d.com/Packages/com.unity.ml-agents@4.0/manual/Sample.html

This is definitely wrong. You're not supposed to use the Agent base class.

[glass iris]

It doesn't move and when I lift it, it falls down sharply.

[onyx flint]

This doesn't look like the sample scene from the docs.

[glass iris]

I don't have any of their scenes, and if I download them from GitHub, everything is pink, there are no models or textures.

[onyx flint]

The samples should be installable with the package(might need to click the samples button in the package manager).

Environments are located in Project/Assets/ML-Agents/Examples

https://docs.unity3d.com/Packages/com.unity.ml-agents@4.0/manual/Learning-Environment-Examples.html

As for everything being pink, you probably need to convert the materials to use shaders of your selected render pipeline. This is a completely different and unrelated issue that you should know how to solve.

[glass iris]

There's a script error and everything is rosy.

[glass iris]

clicked and here it is

[onyx flint]

I explained about pink - it's the materials not being compatible with your render pipeline.
As for the errors this is probably some missing package.

Probably Recorder package.
https://docs.unity3d.com/Packages/com.unity.recorder@5.1/manual/index.html

It seems to be listed in the package dependencies, so it was supposed to be installed with the ml agents package.🤔

Ah, nevermind. It's listed in the github repo packages manifset, not the dependencies. So you need to install it manually.

[glass iris]

I saw in the documentation that they have a CPU, but I don’t have one. Maybe that’s the problem?

[onyx flint]

I can see many problems, like the model reference missing, Agent component assigned. Your setup is not correct at all. Did you have a look at the samples yet or not? You should look at the samples, and read the documentation to understand how to use the package...

[glass iris]

I added the Decision Requester component and it started flying around the map.

[glass iris]

I don't understand at all what I'm doing
