- Moved all postinstallation config file and model munging code out
of the CLI and into a separate script named `invokeai-postinstall`
- Fixed two calls to `shutil.copytree()` so that they don't try to preserve
the file mode of the copied files. This is necessary to run correctly
in a Nix environment
(see thread at https://discord.com/channels/1020123559063990373/1091716696965918732/1095662756738371615)
- Update the installer so that an existing virtual environment will be
updated, not overwritten.
- Pin npyscreen version to see if this fixes issues people have had with
installing this module.
- installer now installs the pretty dialog-based console launcher
- added dialogrc for custom colors
- add updater to download new launcher when users do an update
1. resize installer window to give more room for configure and download forms
2. replace '\' with '/' in directory names to allow user to drag-and-drop
folders into the dialogue boxes that accept directories.
3. similar change in CLI for the !import_model and !convert_model commands
4. better error reporting when a model download fails due to network errors
5. put the launcher scripts into a loop so that menu reappears after
invokeai, merge script, etc exits. User can quit with "Q".
6. do not try to download fp16 of sd-ft-mse-vae, since it doesn't exist.
7. cleaned up status reporting when installing models
- Detect when install failed for some reason and print helpful error
message rather than stack trace.
- Detect window size and resize to minimum acceptable values to provide
better display of configure and install forms.
