tfp layers not working

[markub3327]

Hi,

I try to visualise the tfpl.IndependentNormal, but it returns an error:

---

TypeError Traceback (most recent call last) in <cell line: 1>() ----> 1 visualkeras.layered_view(vae, legend=True)

/usr/local/lib/python3.9/dist-packages/visualkeras/layered.py in layered_view(model, to_file, min_z, min_xy, max_z, max_xy, scale_z, scale_xy, type_ignore, index_ignore, color_map, one_dim_orientation, background_fill, draw_volume, padding, spacing, draw_funnel, shade_step, legend, font, font_color) 105 y = min(max(shape[1] scale_xy, y), max_xy) 106 elif one_dim_orientation == 'z': --> 107 z = min(max(shape[1] scale_z, z), max_z) 108 else: 109 raise ValueError(f"unsupported orientation {one_dim_orientation}")

TypeError: can't multiply sequence by non-int of type 'float'

Hi,this is a problem with the pypi hosted version, please install visualkeras directly from GitHub (see #8)

I tried it again with: !pip3 install git+https://github.com/paulgavrikov/visualkeras

Can you call layer.output_shape on the layer that causes the issue and tell me the output?

[markub3327]

Here is complete code for reconstruction of issue:

tfd = tfp.distributions
tfpl = tfp.layers
tfk = tf.keras
tfkl = tf.keras.layers

# Create a stochastic encoder -- e.g., for use in a variational auto-encoder.
input_shape = [28, 28, 1]
encoded_shape = 2
encoder = tfk.Sequential([
  tfkl.InputLayer(input_shape=input_shape),
  tfkl.Flatten(),
  tfkl.Dense(10, activation='relu'),
  tfkl.Dense(tfpl.IndependentNormal.params_size(encoded_shape)),
  tfpl.IndependentNormal(encoded_shape)
])
print(encoder.layers[-1].output_shape)
print(encoder.output_shape)

visualkeras.layered_view(encoder, legend=True)

Result

((None, 2), (None, 2)) (None, 2)

TypeError Traceback (most recent call last) in <cell line: 13>() 11 print(encoder.layers[-1].output_shape) 12 print(encoder.output_shape) ---> 13 visualkeras.layered_view(encoder, legend=True)
