虚拟环境.tf_gpu中没有名为'tensorflow'的模块

Question

我最近在与keras合作，但无法运行jupyter笔记本。我将笔记本元数据更改为

{
  "kernelspec": {
    "name": ".tf_gpu",
    "display_name": ".tf_gpu",
    "language": "python"
  },
  "language_info": {
    "name": "python",
    "version": "3.7.3",
    "mimetype": "text/x-python",
    "codemirror_mode": {
      "name": "ipython",
      "version": 3
    },
    "pygments_lexer": "ipython3",
    "nbconvert_exporter": "python",
    "file_extension": ".py"
  }
}

但是当我执行keras时，它说tensorflow后端，我有tensorflow gpu版本，但是由于找不到tensorflow而出现错误。该如何解决？
