Tensorflow CPU-only:TypeError: unbound method _as_graph_element() must be called with Variable instance as first argument

Question

I use Tensorflow without GPU, only CPU. I installed it with pip install tensorflow . My Ubuntu17 has Python3, but when I pip install tensorflow , It uses Python2.

My code look like this:

h_conv1 = tf.nn.relu(conv2d(x_image, W_conv1) + b_conv1)

I get this error.

TypeError: unbound method _as_graph_element() must be called with Variable instance as first argument (got nothing instead)
[Finished in 2.2s with exit code 1]

What does this mean? Now I'm trying to use python3 instead, could that help?

Answer 1

It is really difficult to understand the error without the context. Maybe your dimensions for either of x_image or W_conv1 are wrong. Maybe you forgot to initialize the weights?

You are more likely to get answers if you add a bit of context (reproducible if possible) code.

Edit: install pip3 and do pip3 install package to install python3 packages (if this is also a part of your question)
