hello igor.fedorov,

this issue has been fixed by upstream tensorflow, https://github.com/tensorflow/tensorflow/pull/30559

also, you may workaround these warning messages by working with version-1.16 of numpy.
for example,

$ sudo pip3 install -U "numpy < 1.17"

here’s documentation for your reference, https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html
thanks

Thank you.
As you said i reinstalled numpy version to 1.16.5.
Now it works correctly.
Thank you.
