I'm using an Alinx Zynq7000 XC7Z100 development board. In the project.tcl, I set the part to xc7z100ffg-2. After synthesis, IP generation, and bitstream generation, I encountered the following error when running part7b:

y_hw, latency, throughput = nn.predict(X_test, profile=True)

RuntimeError Traceback (most recent call last)
in ()
----> 1 y_hw, latency, throughput = nn.predict(X_test, profile=True)

/home/xilinx/jupyter_notebooks/cnn102/axi_stream_driver.py in predict(self, X, debug, profile, encode, decode)
58 if debug:
59 print("Transfer OK")
---> 60 self.sendchannel.wait()
61 if debug:
62 print("Send OK")

/usr/local/lib/python3.6/dist-packages/pynq/lib/dma.py in wait(self)
215 if error & 0x40:
216 raise RuntimeError(
--> 217 'DMA Decode Error (invalid address)')
218 if self.idle:
219 break

RuntimeError: DMA Decode Error (invalid address)
