It seems like you are trying to install some Python packages. However, I cannot run code in this chat box. If you want to learn more about these packages, feel free to ask.
Tried to copy-paste this commands into my terminal. Got an error saying that `!pip` is not recognized as proper name of a command or script. What can be wrong? I am on windows and used PowerShell to execute these commands
In IPython shells or Jupyter notebooks, the !pip command is often used to execute Python package management instructions inside the shell or notebook. The ! character is not, however, automatically recognized as a legitimate command prefix in a Windows PowerShell terminal. This is due to the specific significance of the ! character in PowerShell's history expansion.

In a Windows PowerShell terminal, you shouldn't use the ! character and should instead type pip before the appropriate command. For instance, you should write pip install package_name> rather than !pip install package_name>.

Here's an illustration of how to use Windows PowerShell's pip to install a package:

Start up Windows PowerShell.

Press Enter after typing pip install package_name>. Put the actual package name in place of package_name>

Type pip install <package_name> and press Enter. Replace <package_name> with the actual name of the package you want to install. For example:

Copy code
pip install numpy

Wait for the package to be downloaded and installed.

Note: If you receive an error that pip is not recognized as a command, you may need to add Python to your system's PATH environment variable. You can do this by following these steps:

Open the Start menu and search for Environment Variables and click on Edit the system environment variables.

Click on the Environment Variables button at the bottom right corner of the System Properties window.

In the System Variables section, scroll down and find the Path variable, then click on Edit.

Click on New and add the path to your Python installation, which should look something like C:\Python37 or C:\Users<username>\AppData\Local\Programs\Python\Python37 depending on your Python version and installation location.

Click on OK to save the changes.

Close and re-open any open PowerShell windows for the changes to take effect.

After adding Python to your PATH, you should be able to use pip commands in PowerShell without encountering the pip is not recognized as a command error.
