Traceback (most recent call last): init .py”, line 4, in **RuntimeError: random_device could not be read
Not sure whats wrong, whenever I try to run my model in a script on cuda device I get this error.
I have tried installing latest to historic versions of pytorch but no luck.
My system has ubuntu 20.04 installed. I am also using tensorflow along with pytorch in the script. I have started facing this issue after upgrading to 20.04 from 16.04.
This would point to a broken installation in the other environment you are using (I don’t know how you are executing the script in the failing case).
I just want to write that I see a very similar problem. I reported it also here:

### 🐛 Describe the bug
Code:
```python
import tensorflow
import torch
```…
This hangs in some cases in the `import torch`.
Importing it the other way around, or also just importing Torch does not hang. However, I'm reporting this here because the stacktrace looks still suspicious.
Specifically, on my system, Ubuntu 22.04, using the distrib Python 3.10, I have TensorFlow 2.12 and PyTorch 2.0.1. Same also with Python 3.11.
The stacktrace of the hang:
```

...
```
The `fd=0`, coming from `std::random_device::_M_getval` looks very suspicious to me. It looks like the `std::random_device` is not properly initialized? Code [here](https://github.com/gcc-mirror/gcc/blob/d156c6054200237b707f9fb44ae9958d926b0745/libstdc%2B%2B-v3/src/c%2B%2B11/random.cc#L582) and [here](https://github.com/pytorch/kineto/blob/6bf8eeb9955a2e975e494ae8dffd2259680e771b/libkineto/src/IpcFabricConfigClient.cpp#L26).
In other cases, I have also seen the error "random_device could not be read". This seems to be very related, maybe it got another uninitialized `_M_fd` value.
I also reported this here: https://github.com/rwth-i6/returnn/issues/1339

I'm posting this because I have not found such stacktrace on Google at all, or any stacktrace related to IpcFabricConfigClient.
What TensorFlow version did you use? I noticed that I get the hang in PyTorch when I use TensorFlow 2.12, but not when I use TensorFlow 2.10. But different CUDA versions/setups might also have influenced this observation.

For me importing torchvision package (or other packages using it) before importing tensorflow solved the problem. Wonder why is this happening…

Some versions of TensorFlow with PyTorch cause this problem. You can try downgrading or upgrading your TensorFlow. For me, it worked by downgrading the TensorFlow
