问题描述
我正在尝试使用Pytorch / XLA运行GCP TPU，我正在使用带有debian-9-torch-xla-v20200818映像的VM，我启动了TPU并使用ctpu状态检查它是否正在运行，这表明两个cpu和TPU正在运行，然后我激活了Torch-xla-nightly环境，但是当我尝试调用此简单代码时：
import torch
import torch_xla
import torch_xla.core.xla_model as xm
dev = xm.xla_device()
t1 = torch.ones(3,3,device = dev)
print(t1)
出现此错误：
Traceback (most recent call last):
File "<stdin>",line 1,in <module>
File "/anaconda3/envs/torch-xla-nightly/lib/python3.6/site-packages/torch_xla/core/xla_model.py",line 231,in xla_device

_DEVICES = xu.LazyProperty(lambda: torch_xla._XLAC._xla_get_devices())
RuntimeError: tensorflow/compiler/xla/xla_client/computation_client.cc:274 : Missing XLA configuration
我尝试了一切，但似乎无济于事。
