Numpy version mismatch in the first try

[mahmoodn]

Hi
I have successfully installed tensorflow and tf-quant-finance from source, however, when I want to run an example, I get an error about version mismatch of numpy.

$ python3 American_Option_Black_Scholes.py
2021-04-02 08:52:17.384836: I tensorflow/stream_executor/platform/default/dso_loader.cc:49] Successfully opened dynamic library libcudart.so.11.0

ImportError: SystemError: <built-in method __contains__ of dict object at 0x7f4c43c1d600> returned a result with an error set

The versions are shown below

$ pip3 list | grep numpy
numpy                   1.19.5
$ pip3 list | grep tensor
tensorboard             2.4.1
tensorboard-plugin-wit  1.8.0
tensorflow              2.6.0
tensorflow-estimator    2.4.0
tensorflow-probability  0.12.1
$ pip3 list | grep quant
tf-quant-finance        0.0.1.dev25

How can I fix that?

Hi Mahmood,

Sorry for the late reply. Could you please clarify how and which example you run?

[mahmoodn]

It seems that there is an incompatibility between tensorflow and numpy 1.20 at the moment.
tensorflow/tensorflow#48271

Closing for now.
