I'm using an imx8mn-evk and I'm using this reference manual: IMX-MACHINE-LEARNING-UG.pdf
I tried to run the PyTorch example pytorch_mobilenetv2.py from the imx-image-full but I got the following error:
" root@imx8mnevk:/usr/bin/pytorch/examples# python3 pytorch_mobilenetv2.py
Traceback (most recent call last):
File "pytorch_mobilenetv2.py", line 7, in <module>
File "/usr/lib/python3.7/site-packages/torch/__init__.py", line 190, in <module>
from torch._C import *
ImportError: /lib/libc.so.6: version `GLIBC_2.32' not found (required by /usr/lib/python3.7/site-packages/torch/lib/libtorch_python.so) "
I have downloaded that version, 2.32 in this way:
wget http://ftp.gnu.org/gnu/glibc/glibc-2.32.tar.gz tar zxvf glibc-2.32.tar.gz cd glibc-2.32 mkdir build cd build ../configure --prefix=/opt/glibc-2.32 make -j4 sudo make install export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/glibc-2.32/lib
However, it did not work.
I guess LD_LIBRARY is not correctly installed but I can't find the error.
Has anyone worked with Pytorch before, and know how to make it run?
Got to this ticket while investigating a similar issue. A couple of comments:
1. This is a known issue, fixed in LF5.10.x. A workaround for 5.4.x is to reinstall the wheel pkgs.
2. eIQ in general, and the example's in the ML User's guide are supported across all i.MX 8 family, not just 8MP. Depending on the platform, the ML compute unit can be different (e.g., for 8MPlus: NPU, GPU or CPU; for 8MNano: CPU). This compute unit can be set through a flag at runtime; for now pytorch only supports the CPU.
The examples in machine learning are for the MX8MPlus, since you have not used this not going to be supported.
Many thanks for your answer.
I have been trying an other alternative: I installed Pytorch in my imx-image-core, first, the version was 1.9.0, wich I got a message about an "Ilegal Instruction" and I achieved to fixed it changing the version to a lower one (1.8.0), however, it was not completely succesful due to this warning: "OpenBLAS Warning : Detect OpenMP Loop and this application may hang. Please rebuild the library with USE_OPENMP=1 option"
Would you know about any more solution to include Pytorch packages to my image in the IMX8mn-evk?
Thanks in advance, I will be waIting for news ASAP.
