如果它不包含文件句柄,我可以pickle这个对象。我希望能够创建文件句柄以访问“A”描述的资源。如果我在类“A”中有一个“open()”方法打开并存储文件句柄供以后使用,那么“A”不再是pickleable。 (我在这里添加打开文件包括一些不能缓存的非平凡索引 - 第三方代码 - 因此在需要时关闭和重新打开并非没有费用)。我...
How is someone supposed to create the string representation of the custom class object? datetime objects happen to offer back and forth string conversion. But that's not the general case. Is someone supposed to use pickle to create the string representation? If not (which I guess not ...

Updated PipelineDataset's documentation to make it clear it is an internal class. ParallelRunStep updates to accept multiple values for one argument, for example: "--group_column_names", "Col1", "Col2", "Col3" Removed the passthru_automl_config requirement for intermediate data usa...
Calling the class like a function generates instances of our new type, and the class’s methods automatically receive the instance being processed by a given method call (in the self argument): >>> bob = Worker('Bob Smith', 50000) # Make two instances >>> sue = Worker('Sue Jones', ...
If you want to try out any of the new features you have seen here, then you do need to be able to use Python 3.8. Tools like pyenv and Anaconda make it easy to have several versions of Python installed side by side. Alternatively, you can run the official Python 3.8 Docker container...
Make python-anyconfig scalable: some functions are limited by max recursion depth. Make python-anyconfig run faster: current implementation might be too complex and it run slower than expected as a result. Documentation: Especially API docs need more fixes and enhancements! CLI doc is non-fulfillin...
# Top-level Makefile for Python # # As distributed, this file is called Makefile.pre.in; it is processed # into the real Makefile by running the script ./configure, which # replaces things like @spam@ with values appropriate for your system. # This means that if you edit Make...
