Now the large language models have been upgraded AutoModelForCausalLM, AutoTokenizer device = "cuda" # the device to load the model onto # Now you do not need to add "trust_remote_code=True" model = AutoModelForCausalLM.from_pretrained( "Qwen/Qwen1.5-7B-Chat", tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen1.5-7B-Chat") # Instead of using model.chat(), we directly use model.generate() # But you need to use tokenizer.apply_chat_template() to format your inputs

at their default values, but note that the board thickness value will be used when exporting a 3D model of the board, and layer thicknesses will be included in net length calculations for any nets that configured in the Editing Options section of the PCB Editor preferences. You can adjust the grid size using the grid dropdown in the top toolbar or by right-clicking and selecting a new grid from the specific fields to update or not update, which properties of the fields to update (text, visibility, size and style, and position), and how to handle fields that are missing or empty in the library footprint

3D modeling and animation tools within the reach of the general computing public. NaN’s business model involved providing commercial products and services around Blender. In 1999 NaN attended its first theme to use (must refer to a locally installed cursor). XCURSOR_SIZE The cursor size, defaults to 28, you may wish to increase the size on Hi-DPI displays. Known Limitations Gnome Shell’s Fractional Using fractional under older versions of Gnome-Shell may result in glitches such as a small cursor size. NVidia GPU Currently NVidia drivers don’t fully support features needed for Wayland. Graphical

NOTE 所有的文本都有可调整的字体、颜色、大小、黑体和斜体强调，左右对齐，以及垂直和水平方向。文本框还支持水平 居中，垂直对齐选项，以及彩色边框和填充。 NOTE The default text size can be set for a schematic in Schematic Setup, and the default font can be set in Preferences. 链接

mask layers matching their copper layer. NOTE It is not possible to define a different pad shape or size on different copper layers in the current version of KiCad. Specify pad to die length: This setting and size as the pad shape on the copper layer(s). In the PCB manufacturing process, the manufacturer will often change the relative size of mask and paste apertures relative to the copper pad size, but but since this size change is specific to a manufacturing process, most manufacturers expect the design data to be provided with the apertures set to the same size as the copper pads. For specific situations

This is the recommended grid for placing symbols and wires 以外的网格尺寸将导致原理图 没有正确的连接！。 NOTE 符号、导线和其他没有对准网格的元素，可以通过选择它们，点击右键，并点击 将元素对准网 格，将它们重新对准网格。 You can adjust the grid size by right-clicking and selecting a new grid from the list in the Grid submenu.
