Pytorch，Pandas，Numpy在Windows和Linux上的不同结果
Pytorch，Pandas，Numpy在Windows和Linux上的不同结果
提问于 2022-08-16 08:43:00
我们正在进行一个人工智能项目，其中包括计算躺在床上的人体的位置。外部支持者为我们提供了一个代码包来完成这项工作，并计算出身体的实际位置(由摄像机检测到)和预测的位置之间的偏差。
该代码包是在Windows上开发的，现在需要移植到Ubuntu20.04。到目前为止，在Ubuntu的代码包中，我们只是更改了一些路径名(反斜杠为斜杠)以使其工作。
如果我们现在运行完全相同的代码，在Windows 10和Ubuntu下使用完全相同的训练和测试数据，我们会观察到以下奇怪的行为：
在Windows环境下，真实体位与预测体位的偏差为25 as (平均值)，这是一个很好的结果。在Ubuntu中，偏差为150 is (平均值)，这是一个不可用的结果。
我们还在相应的Ubuntu机器上运行Windows 10 VM (Virtualbox)中的Windows代码包。结果与我们在“平原”Ubuntu下运行代码时得到的结果非常接近(不可用)。
在Ubuntu下运行时，无论我们使用CPU还是GPU，都没有区别。
代码用Python 3编写，并在Anaconda 3虚拟环境中在Python3.7.12下执行。
我们假设Linux/Ubuntu不完全支持某个CPU指令集。但最后，我们对这种行为并没有一个解释。有谁有主意吗？
我们的CPU：
英特尔核心I7 (凯布湖)
我们的conda env.yaml：

经过更深入的研究，我们发现了由于python中os.listdir()的不同处理而导致的数据准备方面的错误。windows和linux机器上的顺序是不一样的。

如果您想要在您的环境中解决更多的一致性，那么添加专属性到您的YAML。我建议通过小版本的来指定对您很重要的每个包。这是Snakemake社区中Conda的what is recommended。
而且，通道顺序没有意义，而且可能是不一致的根源。如果使用PyTorch，那么pytorch通道绝对应该是最高优先级。而且，anaconda是defaults的一个子集，所以这是不必要的。我会把频道改到：
channels:
- pytorch
- conda-forge
- defaults
- nodefaults最后的nodefaults是一个指令，可以忽略任何系统或用户级配置的通道，确保只考虑YAML通道。

我想在conda env中有一些版本问题。使用python 3时，conda管理与env兼容的所有包。因此，当您使用python3.7时，包将被更新。每个包都有不同的版本。我可以建议你要么使用码头集装箱要么使用码头集装箱。
