Hello,

I’m trying to install PyTorch on JetPack-4.6
And numpy module isn’t possible to install.
It was no problem until 2~3 weeks ago at least when I did.

These are error messages.

Error compiling Cython file:
/------------------------------------------------------------

     self._bitgen.state = <void *>&self.rng_state
     self._bitgen.next_uint64 = &philox_uint64
                                ^

And this is the full log to install numpy.

Hi,

Could you try NumPy 1.19.4?

$ sudo apt-get install python3-pip
$ pip3 install Cython
$ pip3 install numpy==1.19.4

Thanks.

There are same error in 1.19.4, 1.19.3 and 1.19.0.

@sumin.lee1 just a hunch - try pip3 install 'Cython<4' first

6

Same version of Cython is installed. (cython-3.0.0)

@sumin.lee1 hmm I’m not sure if it is something else about your environment then - hard to say? The container builds for numpy and pytorch on JetPack 4.6 are passing:
