Tensorflow hash error during installation (pip)

I am trying to install tensorflow on in a Docker Container on a RB Pi Zero. I get some weird hash-error, see below. What can I try next?

root@123456:/# sudo pip3 install --no-cache-dir tensorflow

I've tried to remove files in 'rm -rf /var/lib/apt/lists/partial' and performed apt-get update&upgrade, but with same result. What can I try next?

Update

The hashes were fixed, so the hash mismatch warning should be gone now.

Original answer

Unfortunately, this is a common issue with https://www.piwheels.org when large wheels are uploaded. If you take a close look at the simple URLs of tensorflow wheels, you'll notice that the wheels

tensorflow-1.14.0-cp36-none-linux_armv7l.whl
tensorflow-1.14.0-cp36-none-linux_armv6l.whl
tensorflow-1.14.0-cp35-none-linux_armv7l.whl
tensorflow-1.14.0-cp35-none-linux_armv6l.whl
tensorflow-1.14.0-cp34-none-linux_armv7l.whl
tensorflow-1.14.0-cp34-none-linux_armv6l.whl

all have the same sha256 hash in download links, which means the hashes are just wrong. The workaround is to download the wheels to and install from disk:

$ wget https://www.piwheels.org/simple/tensorflow/tensorflow-1.14.0-cp35-none-linux_armv6l.whl
$ pip install tensorflow-1.14.0-cp35-none-linux_armv6l.whl

I have also reported wrong hashes here, so the issue will be fixed sooner or later.
