functionality. PyTorch also includes standard defined neural network layers, deep learning optimizers, data loading utilities, and multi-gpu, and multi-node support. Functions are executed immediately instead nvcr.io/nvidia/ pytorch:-py3 Note: If you use multiprocessing for multi-threaded data loaders, the default shared memory segment size with which the container runs might not be enough To pull data and model descriptions from locations outside the container for use by PyTorch or save results to locations outside the container, mount one or more host directories as Docker® data volumes

aspects of the training pipeline like data augmentation, layer and channel configurations can also be parameterized using hyperparameters. For example, when using image data augmentation with rotation, we can might also have additional parameters which could be searched as well. transformation parameters in data augmentation layer contribute to performance improvements while others like learning rate, batch layers.Dense(size, activation='relu'), layers.Dense(5, activation='softmax') ]) Our model, input data and the hyperparameter trial set is ready. Let's go ahead and train the model, each time choosing

models and multimodal models are pretrained on large-scale multilingual and multimodal data and post-trained on quality data for aligning to human preferences. Qwen is capable of natural language understanding 首先使用 ChatML 模板对其进行格式化。例如： data = [] for msg in messages: msg = c['messages'] text = tokenizer.apply_chat_template(msg, tokenize=False, add_generation_ �→prompt=False) data.append(text.strip()) 其中每个 named Qwen..."} ] 然后只需通过一行代码运行校准过程： model.quantize(tokenizer, quant_config=quant_config, calib_data=data) 最后，保存量化模型： 14 Chapter 1. 文档 Qwen model.save_quantized(quant_path, safetensors=True, shard_size="4GB")

Deep learning is becoming more popular in data science fields like robotics, artificial intelligence(AI), audio & video recognition and image recognition -U scikit-learn Seaborn Seaborn is an amazing library that allows you to easily visualize your data. Use the below command to install: pip install seaborn You could see the message similar as specified json { "image_data_format": "channels_last", "epsilon": 1e-07, "floatx": "float32", "backend": "tensorflow" } Here,  image_data_format represent the data format.  epsilon

tensor 理解为是“data”。 我们需要先导入 pytorch，顺便导入 numpy： import torch import numpy as np 现在我们尝试将 list 或者 np.array 转换为 pytorch 的数组： data1 = [ [ 1 , 2 ] , [ 3 , 4 ] ] data_tensor = torch . tensor ( data1 ) print print ( data_tensor . shape ) np_array1 = np . array ( data1 ) data_tensor = torch . from_numpy( np_array1 ) print ( data_tensor . shape ) 输出都是： torch . Size ( [ 2 , 2 ] ) 对于二维 tensor 之间的相乘，@ 和 .matmul 7 y = data_tensor @ data_tensor .T print (y) y = data_tensor ∗ data_tensor print (y) 输出分别是： [ [ 5 , 11] , [11 , 2 5 ] ] [ [ 5 , 11] , [11 , 2 5 ] ] tensor 可以转化为 numpy： np_array2 = data_tensor
