如上所述,你应该使用 numpy.errstate 而不是 scipy.errstate。确保你的代码中正确地导入了 numpy 并使用了 errstate。 考虑版本问题: 虽然在这个特定情况下,版本问题不太可能是导致错误的原因(因为 errstate 从来就不是 scipy 的一部分),但如果你遇到其他与版本相关的问题,考虑更新或降级 scipy 或numpy 库可能是一...
While it is threadsafe, the with statement gives the false impression that it's always safe. It is not: import asyncio import numpy as np def divide_by_zero(): np.float64(1) / 0 async def foo(): for j in range(3): with np.errstate(divide...
It happens when trying to create numpy.random.RandomState instances concurrently in different threads. Below is a minimal reproducer: Reproduce the code example: from concurrent.futures import ThreadPoolExecutor import numpy as np def build_rngs(*ignored): return [np.random.RandomState(i) for i in...
Python numpy errstate用法及代码示例本文简要介绍 python 语言中 numpy.errstate 的用法。 用法: class numpy.errstate(**kwargs)用于浮点错误处理的上下文管理器。使用errstate 的实例作为上下文管理器允许该上下文中的语句以已知的错误处理行为执行。进入上下文后,错误处理将使用 seterr 和 seterrcall 设置,退出时将...
# 需要导入模块: import numpy [as 别名]# 或者: from numpy importerrstate[as 别名]def__call__(self, transform_xy, x1, y1, x2, y2):x_, y_ = np.linspace(x1, x2, self.nx), np.linspace(y1, y2, self.ny) x, y = np.meshgrid(x_, y_) ...
データに問題があるケースでは、値にnanやinfが発生しているケースがあり、infの場合はこの「np.errstate(all="raise")+標準化」でエラー箇所を特定できる、ということでした。参考になれば幸いです。 36 Register as a new user and use Qiita more conveniently ...
Unfortunately, these are less fine-grained than I would like because some of the tests have many lines of the form `assert_array_equal(pandas_expression_to_test, expected_raw_numpy_expression)` where `expected_raw_numpy_expression` is what is triggering the warning. It was tedious to try ...
