Bug summary
Hi i am trying to plot an image using the plt.imshow() function.
Code for reproduction
base64_data = req.get("base64")
decoded = Image.open(BytesIO(base64.b64decode(base64_data)))
arr = cv2.cvtColor(np.array(decoded), cv2.COLOR_BGR2RGB)
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
ret, threshold = cv2.threshold(gray, 100, 255, cv2.THRESH_BINARY)
plt.axis("off")
plt.imshow(image)
plt.show()Actual outcome
2018-10-24 10:11:40.636 python[69065:3191133] It does not make sense to draw an image when [NSGraphicsContext currentContext] is nil. This is a programming error. Break on void _NSWarnForDrawingImageWithNoCurrentContext(void) to debug. This will be logged only once. This may break in the future.
Expected outcome
A plot with the image.
