在 cupy 中执行以下最小示例。

import cupy, cupyx

x = cupy.array([1., 2., 3.])
y = cupy.arange(10)
print(cupyx.get_runtime_info())

以下列方式

(venv) user@ailx216:/work/sandbox$ CUDA_PATH=/usr/local/cuda-9.1 python cupy_test.py

给了我一个奇怪的磁盘配额超出错误。

Traceback (most recent call last):

我的设置是

我的 anaconda 安装在 A./home/sysdata/USR/anaconda3 我的工作目录是 B./work/sandbox

两者都有足够的磁盘配额。我该如何调试呢？编辑：通过清除临时目录来解决此错误。

但是现在我得到了错误：

  File "chainer_test.py", line 14, in <module>
    mydata_like = xp.zeros_like(mydata)
/cupy/creation/basic.py", line 205, in zeros_like
    order, strides, memptr = _new_like_order_and_strides(a, dtype, order)
/cupy/creation/basic.py", line 35, in _new_like_order_and_strides
    order = chr(_update_order_char(a, ord(order)))
TypeError: Argument 'x' has incorrect type (expected cupy.core.core.ndarray, got numpy.ndarray)

print( cupyx.get_runtime_info() ) 的输出如下：

即使有足够的磁盘空间，也可能发生“超出磁盘配额”。

一种可能性是 inode 限制：https ://superuser.com/questions/959175/disk-quota-exceeded-when-writing-to-tmp-but-plenty-of-space-linux

如果清除 cupy 内核缓存 (at ~/.cupy/kernel_cache) 会怎样？
