I have the following pytorch installation error. Could anyone help ?

I encountered the same issue today and got around it by updating my qnnpack submodule.

```auto
cd third_party/QNNPACK
git pull origin master

```

As it worked with the current master branch I haven’t spent more time thinking about which version qnnpack should be updated to.

If this does not work, you may also consider disabling qnnpack build, there is a NO\_QNNPACK option but I haven’t tried it.

I have followed your suggestion regarding QNNPACK , but I faced some other error as follows:

Do you have any idea ?

I didn’t have this problem. pybind11 is also a submodule of pytorch so it may be worth trying to update it too ?  
The following command will update all submodules

```auto
git submodule update --recursive

```

I have pulled the latest commit for pybind11 , but the problem still persists. Why ?
