"Explain the text in one sentence. \n Text:(CNN) -- A federal judge Friday ruled in favor of a former UCLA college basketball star who sued to end the NCAA's control over the rights to college athletes' names, images and likenesses.\n\nIn a landmark decision, U.S. District Judge Claudia Wilken sided with Ed O'Bannon in his lawsuit against the National Collegiate Athletic Association. O'Bannon argued athletes in the top tier of college basketball and football should be allowed to profit from their schools' use of their likenesses.\n\nIn a 99-page ruling, Wilken wrote that current NCAA rules \"unreasonably restrain trade in the market for certain educational and athletic opportunities offered by NCAA Division I schools.\"\n\nWilken issued an injunction to block the NCAA from prohibiting its member schools and conferences from offering their Football Bowl Subdivision or Division I basketball recruits a limited share of the revenues generated from the use of their names, images, and likenesses.\n\nShe did rule, however, that the NCAA could set a cap on the money paid to athletes, as long as it allows at least $5,000 per athlete per year.\n\n\"The NCAA's witnesses stated that their concerns about student-athlete compensation would be minimized or negated if compensation was capped at a few thousand dollars per year,\" the judge wrote.\n\nO'Bannon's suit alleged the waivers the athletes are required to sign are illegal and asked that players be able to collectively negotiate the terms of their likenesses in order to keep a share of those profits.\n\n\"Before the court in this case is only whether the NCAA violates antitrust law by agreeing with its member schools to restrain their ability to compensate Division I men's basketball and FBS football players any more than the current association rules allow,\" Wilken wrote. \"For the reasons set forth above, the court finds that this restraint does violate antitrust law.\"\n\nThe ruling could potentially change college sports drastically, eventually forcing the NCAA to restructure its amateur model and allow college athletes to be paid.\n\nNCAA chief legal officer Donald Remy said: \"We disagree with the court's decision that NCAA rules violate antitrust laws. We note that the court's decision sets limits on compensation, but are reviewing the full decision and will provide further comment later.\"\n\nWilliam Isaacson, an attorney for the plaintiffs, called the ruling \"a big step forward for common decency.\"\n\n\"One of the things the judge is saying here .. is some sharing is OK,\" he said. \"It won't affect amateurism, won't affect the popularity of the sport. She made a very reasonable and significant and measured decision.\"\n\nRamogi Huma, president of the National College Players Association, said the ruling was \"a big win\" that signaled \"the time for college athletes to get their due,\" though he was critical of the $5,000 compensation cap.\n\n\"The ruling says the NCAA was operating illegally and college athletes do have rights,\" said Huma, who helped find players to join the case. \"Even if you label them student-athletes and want to call it amateurism, it doesn't give the NCAA the right to deny them the rights that other Americans deserve.\"\n\nSonny Vaccaro, who started the lawsuit by introducing O'Bannon and lead attorney Michael Hausfeld, said the decision was precedent-setting.\n\n\"The key is, they're allowed to get paid,\" said Vacarro, who helped pioneer branding athletes by putting Nike shoes on Michael Jordan.\n\nVacarro called the decision his most important career accomplishment.\n\n\"It's more important to me that these kids won and this go forward and the principles are right,\" he said. \"To me, it's more important than the Jordan and Kobe and things I did in my professional life. ...This was just something that was wrong and I totally believed in it.\"\n\nThe judge wrote that the injunction will not affect student-athletes who enroll in college before July 1, 2016.\n\nWhen athletes commit to a university, players are required to sign a waiver that relinquishes their right to their own likenesses in every form.\n\nThat means they can't make money off their television appearances, their jerseys, or in any other way.\n\nThe universities get any revenues from selling sports paraphernalia or other material related to the players.\n\nThe trial began June 9 in federal court in Oakland, California. The plaintiffs were 20 current and former student athletes who play or played for an FBS football or Division I men's basketball team starting in 1956.\n\nLegal appeals could delay a final outcome for years but the decision is in a position to be the first major NCAA reform effort to take hold.\n\nAlready the issues brought up in the case have had an effect, even before the ruling was made.\n\nTexas A&M, the University of Arizona and Northwestern University have decided to stop selling jerseys with the numbers of specific players.\n\nInstead, Texas A&M will sell the number 12 jersey, in keeping with its 12th man tradition; and Arizona will sell jerseys with numbers that correspond to the year of competition -- 14 for this year, according to a school spokesman. Northwestern will sell only jersey number 51, in honor of its head coach, Pat Fitzgerald, and legendary Chicago linebacker Dick Butkus.\n\nThe NCAA's argument in both the ongoing O'Bannon suit and another one filed by former quarterback Sam Keller, also in federal court in Oakland, is that it is trying to protect the amateur model of college sports.\n\nPaying college athletes would hurt traditions, NCAA chief testifies\n\nNCAA under fire: 5 things to know\n\nNCAA faces change, legal challenges in months ahead\n\n"

前提条件
完成腾讯云 TI-ONE 训练平台 的服务注册与开通,请参考 账号与权限说明。完成腾讯云 私有网络 服务注册与开通,并完成私有网络创建,请参考 创建私有网络。
一、新建 CFS
CFS(Cloud File Storage, CFS) 文件存储系统官方介绍:CFS 介绍文档,CFS 产品控制台。您新建的 CFS 文件存储系统在 TI 上的使用场景:您用于精调大模型的业务数据需要上传到 CFS(您也可直接使用 TI 内置示例数据快速启动精调训练任务)。大模型精调过程中,会产生一些模型中间结果(Checkpoint)、以及精调后最终得到的业务大模型等需要存储到您的 CFS 。
若您已有自己的 CFS 文件存储系统则可跳过本步骤;若无,则可参考以下操作新建您的 CFS 。
“新建 CFS 文件存储系统”的具体操作:1. CFS 产品控制台 ,在文件系统二级页面,单击创建按钮,选择适合您的“文件系统类型”(本示例选择了“通用标准型”),然后配置详细参数,本示例配置如下:
2. 待创建的“llm-sft-demo”文件系统状态变为“可使用”后,您后续在 TI 平台上就可使用此 CFS 挂载您的精调训练任务了。
二、挂载 CFS
本步骤的操作原因:因为第一步中您新建的 CFS 下还只有一个根目录,您需要更好的组织 CFS 中的目录层级结构用于区分不同训练任务的不同输出路径,比如在根目录下新建一个“/sft-demo-20230825”的子目录作为本示例训练任务的输出路径。若您希望用自己的业务数据精调大模型,则您也需要挂载 CFS 后,将训练数据文件上传到 CFS 中。
1. 新建 Notebook 实例并挂载用户 CFS 用户进入 腾讯云 TI 平台 ,在训练工坊 > Notebook二级页面,单击新建按钮,新建一个 Notebook 实例,且将用户的 CFS 配置挂载到该容器实例上,参数如下,请重点注意,您此时新建的 Notebook 所在地域需要和第一步中新建的 CFS 所在地域保持一致。备注:此时选择的“镜像”可在“内置镜像”中任意选择,因为该 Notebook 仅用于挂载 CFS 、可视化的管理 CFS 上的文件信息,对镜像中安装的依赖包没有特殊的要求。此时选择的“算力规格”可用较小的“2C4G”启动 Notebook, 因为这个资源仅仅用于启动 Notebook 实例而不是最终大模型精调所用的训练资源。2. 进入运行中的 Notebook等待您新建的 Notebook 实例状态处于“运行中”后,单击操作 > 打开按钮,进入Notebook页面此时,您就可以通过 Notebook 界面,直接操作您的 CFS 文件系统了。您有 3 种操作场景:新建文件夹:管理 CFS 上的文件目录,如新建一个“sft-demo-20230825”的文件夹后续用于作为本示例训练任务的输出目录。上传本地文件到 CFS:若您希望用自己存储在本地的业务数据精调模型,则您可在此界面上传本地数据文件到 CFS。当然您也可直接使用平台为您内置的示例数据作为训练数据。拉取 COS 数据到 CFS:打开“Terminal”,执行 coscmd 的相关命令,实现将存储在 COS 中的业务数据文件拉取到 CFS 文件系统中。可参考 COSCMD 工具 产品文档。
三、快速试一试,选型基底模型
1. 一键部署基底模型用户进入 腾讯云 TI 平台 ,在大模型精调二级页面,选择您希望快速试一试模型效果的卡片,单击进入卡片详情。本示例以试一试“llama-2-7b-chat模型”为例,单击新建在线服务按钮,启动服务配置页面单击后,平台会自动为您跳转到模型服务 > 在线服务的创建服务参数配置页面。本页面重点参数配置如下:(其余参数都可使用默认值,不修改或按需修改)服务名称:输入您的自定义服务名称。计费模式:部署大模型推理服务支持“按量计费”和“包年包月”两种模式都可以。本示例采用“按量计费”。服务实例模型来源:选择 “镜像”类型。模型和运行环境:系统已为您内置默认填充了“内置大模型/llama系列/llama_2_7b_chat_hf”。算力规格:本示例选择 20C80G T4*1 的机器配置,此外还支持V100、A100、A10 等机型(裸金属机型不支持)。单击同意开源大模型的相关法律协议后,即可单击启动服务按钮。2. 在线体验模型效果创建服务后,前端自动返回模型服务 > 在线服务列表页面,待大模型服务状态为“运行中”中后,表示服务已成功启动运行。您可以通过单击操作 > 在线体验按钮进入模型快速体验页面,通过问答形式测试基底模型。若您后续使用平台内置示例数据进行精调训练,则可尝试以下问题体验精调前基底模型效果。测试 prompt1 内容:

She made a very reasonable and significant and measured decision.\"\n\nRamogi Huma, president of the National College Players Association, said the ruling was \"a big win\" that signaled \"the time for college athletes to get their due,\" though he was critical of the $5,000 compensation cap.\n\n\"The ruling says the NCAA was operating illegally and college athletes do have rights,\" said Huma, who helped find players to join the case. \"Even if you label them student-athletes and want to call it amateurism, it doesn't give the NCAA the right to deny them the rights that other Americans deserve.\"\n\nSonny Vaccaro, who started the lawsuit by introducing O'Bannon and lead attorney Michael Hausfeld, said the decision was precedent-setting.\n\n\"The key is, they're allowed to get paid,\" said Vacarro, who helped pioneer branding athletes by putting Nike shoes on Michael Jordan.\n\nVacarro called the decision his most important career accomplishment.\n\n\"It's more important to me that these kids won and this go forward and the principles are right,\" he said. \"To me, it's more important than the Jordan and Kobe and things I did in my professional life. ...This was just something that was wrong and I totally believed in it.\"\n\nThe judge wrote that the injunction will not affect student-athletes who enroll in college before July 1, 2016.\n\nWhen athletes commit to a university, players are required to sign a waiver that relinquishes their right to their own likenesses in every form.\n\nThat means they can't make money off their television appearances, their jerseys, or in any other way.\n\nThe universities get any revenues from selling sports paraphernalia or other material related to the players.\n\nThe trial began June 9 in federal court in Oakland, California. The plaintiffs were 20 current and former student athletes who play or played for an FBS football or Division I men's basketball team starting in 1956.\n\nLegal appeals could delay a final outcome for years but the decision is in a position to be the first major NCAA reform effort to take hold.\n\nAlready the issues brought up in the case have had an effect, even before the ruling was made.\n\nTexas A&M, the University of Arizona and Northwestern University have decided to stop selling jerseys with the numbers of specific players.\n\nInstead, Texas A&M will sell the number 12 jersey, in keeping with its 12th man tradition; and Arizona will sell jerseys with numbers that correspond to the year of competition -- 14 for this year, according to a school spokesman. Northwestern will sell only jersey number 51, in honor of its head coach, Pat Fitzgerald, and legendary Chicago linebacker Dick Butkus.\n\nThe NCAA's argument in both the ongoing O'Bannon suit and another one filed by former quarterback Sam Keller, also in federal court in Oakland, is that it is trying to protect the amateur model of college sports.\n\nPaying college athletes would hurt traditions, NCAA chief testifies\n\nNCAA under fire: 5 things to know\n\nNCAA faces change, legal challenges in months ahead\n\n"
